Technical and Commerical Issues Governing the Development of Thermotropic Liquid Crystal Polyesters in the 1990s 2 Volume Set

Book Description

In recent years, studies by both industry and academic researchers have opened the door to improving performance and reducing costs of these new materials. The particular structure and morphology of LCPs, as well as their peculiar rheological behavior, have stimulated researchers to develop new theoretical models and new characterization and processing techniques to more fully understand and utilize LCPs. Although the scientific literature is very rich in data on the synthetic techniques and on the relations between structure and phase behavior of these new polymers, the understanding of the rheological and processing aspects is still far from satisfactory-particularly in the case of LCP blends. In fact, although an appreciable number of patents and scientific papers have appeared describing the phase behavior, the rheology, and the mechanical properties of many of these polyblends, several aspects of the relations between processing and morphology, and between morphology and properties of these materials are still obscure or even controversial. Now, this new book, written by leading researchers, provides an up-to-date guide and reference to the processing, rheology and applications of pure LCPs and LCP blends. The book concisely reviews the synthetic procedures for the production of LCPs and discusses the rheological behavior and processing methods. Plus, the book examines present and future applications areas of LCPs and LCP blends.

Book Description

"Thermotropic Liquid Crystals: Recent Advances" covers developments in the field of thermotropic liquid crystals and their functional importance. In addition it presents advances related to different sub-areas pertinent to this interdisciplinary area of research. This text brings together research from synthetic scientists and spectroscopists and attempts to bridge the gaps between these two areas.

Recent studies have reported a plethora of novel mesogenic molecules which triggered new interest in this area of research. Use of design concepts such as microphase segregation, non-covalent interactions, dipole-dipole interactions and shape anisotropy enabled the incorporation of any chemical structure into a liquid crystal. As a result, a range of exciting molecules such as columnar liquid crystals that lack side chains, liquid crystalline dendrimers, and unusually shaped amphiphilic molecules have been made. Characterization of these surprising molecules poses a tremendous challenge to existing physical techniques.

This comprehensive text has chapters covering the applications of high-resolution methods, such as solid-state NMR, that have been used to understand the high-resolution structure, dynamics, orientation, and orientational order of these molecules in various phases.

This book will prove to be an invaluable resource to students, researchers, and academics active in Chemistry, Material Science, and Nano-science programs. It will also be of interest to Scientists from industries that focus on this research.

From the author: Shear-induced chain orientation and relaxation of chain orientation in a thermotropic liquid-crystalline poly(4-hydroxybenzoic acid (73 mol%)-co-2-hydroxy-6-naphthoic acid (27 mol%)) (Vectra A950) were studied by means of transmitted light intensity through crossed polarizers in a shear cell. Shear rates ranged between 4 and 1000 [s.sup.-1] and the level of chain orientation increased with increasing shear rate and increasing temperature. Overall, the times for relaxation were very short. The longest relaxation times ([approximately]21s) were obtained at the lowest shear temperatures and at intermediate shear rates. At high shear rates, the relaxation times were generally short ([approximately]2s) and independent of temperature. The rapid relaxation of orientation after high rate shearing (100-1000 [s.sup.-1]) indicates that shear-induced crystallization is inhibited under these conditions. A certain degree of chain orientation was still present although the relaxation as judged by the transmitted light intensity was complete. Signs of recrystallization were observed if the samples were not preheated to 320 [degrees] C prior to shearing. By simultaneous shearing and cooling, high degrees of orientation were achieved (f [similar to] 0.7) as revealed by X-ray diffraction and infrared dichroism. Infrared spectroscopy showed that annealing of oriented samples at 250 [degrees] C led to an increase in thermal stability of the orientation with annealing time.

From the author: Blends of poly(butylene terephthalate) (PBT) with three different thermotropic liquid crystalline polyesters (TLCPs) were prepared. The first TLCP (HBH-6) consists of diad aromatic ester type mesogenic units and the hexamethylene spacers along the main chain, and the second (TB-S6) is a wholly aromatic polyester TLCP having alkoxy side groups on the terephthaloyl moiety. The last (TR-4,6) is an LC copolymer consisting of triad aromatic ester type mesogenic units and two different spacers; tetramethylene and hexamethylene units. Blends of TLCP with PBT were melt spun at different LCP contents and different draw ratios to produce monofilaments. For the HBH-6/PBT and TB-S6/PBT blends, the ultimate tensile strength showed a maximum value at the 5 wt% level of LCP in the blends, and then it decreased when the LCP content was increased up to 20%. On the other hand, the initial modulus monotonically increased with increasing LCP content in all cases. The blends with TB-S6 showed the highest tensile properties of the three blend systems. This can be ascribed to the highest rigidity of the polymer chain, which still carries relatively long alkoxy substituents that promote sufficient adhesion between the LCP and PBT matrix. When compared with the PBT fiber itself, the fibers obtained from the 5% TB-S6/PBT blend exhibited an improvement in tensile strength by [greater than] 250% and in tensile modulus by [approximately] 200%.

From the author: The compatibilization by transesterification of aromatic thermotropic liquid crystal polyesters (Ar-TLCP's) and TLCP's containing aliphatic ethylene-terephthalate (ET) linkages has been studied. Three Ar-TLCP's were mixed with two p(ET/HBA)'s, each having different extents of blockiness, to form a series of binary blends (Bin-TLCP's). The morphology and physical properties of the resultant Bin-TLCP's depend on the block structures, compositions, viscosities, and susceptibility to transesterification of the components. In this work, the influence of TLCP block structure and transesterification on the compatibility of the components of the Bin-TLCP's is described.

Book Description

When first published (in Russian), this book proved to become the fountainhead of a major stream of important papers in mathematics, physics and even chemistry. Indeed, it formed the basis of new methodology and opened new directions for research. The present English edition includes new examples of applications to physics, hitherto unpublished or available only in Russian. It uses topological methods to analyze isotropic invariant manifolds in order to obtain symptotic series of eigenvalues and eigenvectors for the multi-dimensional Schrödinger equation also taking into account the so-called tunnel effects.

Book Description

Paul Christopher, at the height of his powers as a secret agent, believes he knows who arranged the assassination and why. His theory is so destructive of the legend of the dead president, though, and so dangerous to the survival of foreign policy that he is ordered to desist from investigating. But Christopher is a man who lives by and for the truth, and his internal compunctions force him to the heart of the matter. He resigns from the Agency and embarks on a tour of investigation that takes him from Paris to Rome, Zurich, the Congo, and Saigon. Threatened by Kennedy's assassins and by his own government, Christopher follows the scent of his suspicion - one breath behind the truth, one step ahead of discovery and death.

Blowback!.......2007-08-20

Reading the synopsis of this novel I nearly skipped it because I didn't want to read another crackpot Kennedy assassination theory. However, I have recently become a fan of Charles McCarry's Paul Christopher novels so I gave it a go anyway. I have to say I didn't read this as quickly as is my wont, and it is a dense novel with many characters. However, the end result is a very credible story of who might have been behind the murder; but more than that, it read true as to the background of characters and settings from Italy to Viet Nam to the Congo in that period.

I only recently became aware of some of the revisionist history being written concerning the assassinations of the Ngo brothers in Viet Nam and how that was a real turning point in the war, with everything downhill from that point on. McCarry was writing a lot of this as fiction 30 odd years ago. Interesting. He presents an understanding of Vietnamese culture I had never encountered before, and it was very enlightening.

Filled with nefarious characters, a "rendition" kidnapping, revolutionaries, double agents and intrigue aplenty, there is also a nicely detailed love story of Paul Christopher and his Molly that fills out a tale that has the feel of real people and places and real history being made. I am working my way through the series, and although what was recent history when written in 1975 is now almost ancient history, it is a good starting place to enter the world of Paul Christopher and Charles McCarry. Well worthwhile.

Top Secret -- Need To Know.......2007-06-26

I first read this in 1975. I started reading in the early evening, read it straight through to the end. Stunned by the breathtaking authenticity, I read it through again, immediately, entirely.

When I looked up, the sun was shining through my window. I had been at it for over 16 hours.

This book became my benchmark for its genre.

I am a student of the CIA, especially the 1960s evolution of the Agency. Today the head of the Clandestine Service (also then euphemistically called the Deputy Director of Plans, and today called the Deputy Director for Operations) would never dream of meeting a CIA officer in the street, but in the 1960s it was a practice. The episodes in the Congo were authentic. The tradecraft was authentic. The rivalry between the Agency and the military Special Forces continues to this day.

The book is probably authentic to a fault. One reviewer complains that the reader is kept in suspense because the author keeps secrets already know to his characters from the reader.

But isn't that what secrecy is all about? Even the reader, after all, is not entitled to know everything. Need to know. I found that an outstanding literary device, given the genre of the book.

There's more on this theme. McCarry's next book, The Secret Lovers, actually takes place before The Tears of Autumn. But the two stories dovetail together, and this second (but chronologically earlier) book deliciously dovetails with The Tears of Autumn, and even innocuously explains secrets that were left hanging in the Tears of Autumn.

McCarry was actually a field officer of the CIA, operating covertly in Europe, Africa and Asia. He knew of what he wrote. His description of Feung Shui, the powerful concept of Chinese geomancy, is absolutely spot on. Ask any Asian.

Finally, McCarry's style of leaving all emotion out of his principal character, and his overall writing style, strengthens the overall proposition of the tale. This is an intelligence report. Delivered by an intelligence operative. Take it or leave it. Yes, it reads like a Haiku should -- all the emotion is provided by the reader. The truth itself needs no embellishment.

Excellent spy novel.......2006-08-01

Thankfully this author's books are coming back into print and I have yet to be disappointed with any of them. Without sounding condescending, (or elitist), McCarry's books are "intellectual" thrillers in the best sense - i.e. much like Littell, Furst or early LeCarre - in that they make the reader think and the books are also almost impossible to put down. McCarry's books track Paul Christopher, covert agent in the "The Outfit", who is a multi-lingual, globe-trotting ladies' man, rarely carrys a gun, doesn't drive fast expensive cars and doesn't blow stuff up. On the other hand he knows a lot of people who do all the above (and more), and be them friend or foe, Paul is usually very busy staying at least one step ahead of them. In this volume we find our hero searching for the truth behind the tragic events, both in Vietnam and the U.S., of November 1963, bouncing from continent to continent. (As an aside the view into Vietnamese culture in this book is fascinating). The answer(s) he finds are troubling, creative and seemingly involve everyone but the journey in ascertaining them is what makes this book a great read. Highly recommended.

Who shot JFK? It's obvious!.......2006-05-28

McCarry crafts a more plausible Kennedy assassination theory than most conspiracy devotees. Kennedy countenances (at a minimum) the assassinations of Ngo Dinh Diem and his brother on 1 November 1963 (so says the book; in reality the date was 2 November). Three weeks later, JFK is assassinated in Dallas. US agent Paul Christopher concludes that the Vietnamese did it. He quits the agency and sets out to prove it. The tale sprawls across 4 continents with rapid pacing as he chases down the truth.

The book's interesting characters are mostly believable, at once familiar yet not completely typecast. Christopher is the expert and honest US agent. David Patchens is the honest-broker spy chief. Foley is the JFK worshipper and political operator. The Truong toc is the ancestral head of Diem's family (OK, not so familiar, but intriguing). Luong plays Christopher's trusted agent (guess what happens to him!). And there's a Cuban agent, a Mafia don, a Vietnamese fortune-teller, and more. Molly, Christopher's obligatory love interest, provides important motivation, but is otherwise uninspired.

The book gives readers a peek into Vietnamese culture that is quite interesting. The book also suggests that if the American people had been told the connection between the assassinations that support for the war, not yet fully under way, would have dried up overnight.

Highly recommended for fans of the spy genre.

Best in depth look at Vietnamese culture.......2006-05-08

This is one of the best and most believable Kennedy assassination theory novels that I have read. McCarry takes the reader through the fascinating rituals and cultural idiosyncracies of the ancient Vietnamese people. The story unfolds at a brisk pace with no wasted passages. Paul Christopher is a classic protagonist somewhat similar to Bill Granger's Deveroux in the later November Man series. With diverse characters and various plot lines all coming together in the end, Christopher's startling discoveries are not enough to overcome the fanatical protections of Kennedy's loyal sycophants.
