The Ninth Biennial Polymer Symposium, sponsored by the Division of Polymer Chemistry of the American Chemical Society, was convened during November 18-22, 1978 at Key Biscayne, Florida. The symposium also marks the occasion when the Second Division of Polymer Chemistry Award was presented to Professor C. S. Marvel for his outstanding achievements in polymer chemistry. The proceedings of this Symposium are recorded in this volume. Carl Shipp Marvel, more popularly known as Speed Marvel, was born in Waynesville, Illinois in 1894. He received his A.B. and M.S. degrees at Illinois Wesleyan University, and M.A. and Ph.D. degrees at the University of Illinois. After having completed his graduate education, Professor Harvel remained at the University as a member of the Chem istry faculty. He "retired" from Illinois in 1961, and moved to the University of Arizona where he continued his research in polymer chemistry. Out of the more than 500 publications, over 100 were from Arizona during his active retirement. Speed has so far trained 176 Ph.D. students and 128 postdoctoral fellows, and inspired countless young chemists to the science of macromolecules. No doubt these numbers will increase along with his scientific productivity. Professor Harvel has been honored on numerous ocasions prior to receiving the Division of Polymer Chemistry Award.

The Eleventh Biennial Polymer Symposium of the Division of Polymer Chemistry, Incorporated of the American Chemical Society was held November 20-24, 1982 at -the Cerromar Beach Hotel, Dorado Beach, Puerto Rico. The theme of the meeting was "High Performance Polymers. " On this occasion Professor Herman F. Mark received the Fourth Division of Polymer Chemistry Award for his outstanding achievements and his unique missionary role in the development of Polymer Chemistry. Professor Mark was the premier organizer of many important firsts in polymer chemistry, to name just a few - the first polymer journal, the pre-eminent Journal of Polymer Science; the first U. S. academic center of Polymer Science at the Brooklyn Polytechnic Institute which led to a long procession of eminent polymer scientists; the "High Polymer" Monograph series. In the Division of Polymer Chemistry, he was the first secretary-treasurer and chairman in 1955 •• A detailed biography follows along with Professor Mark's reminiscences on the Early Days of Polymer Science, the topic of his Award lecture. It was indeed a pleasure and ultimate honor to be the Chairman and organizer of the technical program of this Symposium. The fourteen invited lectures are given herein. I have tried and believe succeeded in presenting important current research by leading workers on High Performance Polymers.

Polymers are substances containing a large number of structural units joined by the same type of linkage. These substances often form into a chain-like structure. Starch, cellulose, and rubber all possess polymeric properties. Today, the polymer industry has grown to be larger than the aluminium, copper and steel industries combined. Polymers already have a range of applications that far exceeds that of any other class of material available to man. Current applications extend from adhesives, coatings, foams, and packaging materials to textile and industrial fibres, elastomers, and structural plastics. Polymers are also used for most composites, electronic devices, biomedical devices, optical devices, and precursors for many newly developed high-tech ceramics. This book presents leading-edge research in this rapidly-changing and evolving field.

Collects papers presented at a symposium held in Ft. Lauderdale, Florida, in November 1990, of the Division of Polymer Chemistry of the American Chemical Society. Topics discussed include high performance polymers, polymers for electronic applications, nonlinear optics, polymers from biological sour

APPLIED COATINGS An integrated collection of case studies providing a concise guide for professionals working with coatings materials in academia and industry In Applied Coatings: Chemistry, Formulation, and Performance, distinguished scientist Dr. Weih Q. Lee delivers an illuminating collection of case studies designed to connect various elements of applied coatings technology. Going beyond generic discussions, the author describes the fundamental chemistry, formulations, and properties of applied coating materials – including the structural and functional components of structure-property relationships – as well as the foundations of applied cure kinetics and the rheology of epoxy coatings. Each chapter is self-contained, comprehensive, and can be read individually, while the book remains technically and editorially integrated. Core themes include structure-performance relationships, formulation index driven experiment design, and consolidated thermal analysis. Readers will also find: A thorough introduction to epoxies and epoxy curing agents, including oxetanes, vinyl esters, glycidyl methacrylate (GMA), isocyanate and silicone crosslinkers, cationic catalysts, acrylate and phenol accelerators, and specialty derivatives Attentive descriptions of epoxy curing chemistry, including epoxy-phenolic, -polyamide, -active ester, and acid- or base-catalyzed systems in a broader scope Comprehensive explorations of cure kinetics and rheology, including model-free kinetics (MFK), the nth-order model covering Kissinger plots and the Borchardt—Daniels (BD) approach, the autocatalytic model, executive quantification via curve fitting of DSC (differential scanning calorimetry) exotherms, the rheology of non-reactive fluids, and the viscoelasticity of reactive coatings Practical discussions of C1S thick-film surface coatings, C2S structural lamination, liquid and powder epoxies, and phenolic coatings, including fluorene monomers, heterocyclic resins, and polymerizable derivatives Complete treatments of coating characterization, microencapsulation, epoxy hybrids and non-epoxy platforms, adhesion of applied coatings, and adhesion promotion, including reactive and functional silicones Perfect for formulation and research and development scientists and engineers at any technical level, Applied Coatings will also benefit research professors and students studying coatings, adhesives, composites, electronic materials, and more.

At the beginning of this book, and in the absence of guidance from IUPAC, it is appropriate to clarify the term 'chemical sensor'. A chemical sensor may be defined as a simple-to-use, robust device that is capable of reliable quantitative or qualitative recognition of atomic, molecular or ionic species. It is hard to imagine a field of applied chemistry in which a significant impact could not be made by such a device. Undoubtedly, it is this potential that has fuelled the contemporary preoccupation with chemical sensors. An unfortunate side-effect of this otherwise welcome interest is the use of the term 'chemical sensor' to add the chemical equivalent of a 'High-Tech gloss' to a rather ordinary device, publication, conference or research group. This loose usage of terminology is responsible in part for the ambiguity that surrounds many chemists' concepts of the form and function of chemical sensors. Further ambiguity arises from the extravagant claims that have been made for some sensors, and the impression that has been given of much 'verging-on-a-breakthrough' research. The research chemist engaged in sensor development should be mindful of the fact that the ultimate target for these devices is the real world, and that a successful laboratory device operating under well-defined conditions and careful calibration does not constitute a chemical sensor. Research into chemical sensors is not a recent phenomenon; it has been under way for over 80 years.

To the surprise of practically no one, research and engineering on multi polymer materials has steadily increased through the 1960s and 1970s. More and more people are remarking that we are running out of new monomers to polymerize, and that the improved polymers of the future will depend heavily on synergistic combinations of existing materials. In the era of the mid-1960s, three distinct multipolymer combinations were recognized: polymer blends, grafts, and blocks. Although inter penetrating polymer networks, lPNs, were prepared very early in polymer history, and already named by Millar in 1960, they played a relatively low-key role in polymer research developments until the late 1960s and 1970s. I would prefer to consider the IPNs as a subdivision of the graft copolymers. Yet the unique topology of the IPNs imparts properties not easily obtainable without the presence of crosslinking. One of the objectives of this book is to point out the wealth of work done on IPNs or closely related materials. Since many papers and patents actually concerned with IPNs are not so designated, this literature is significantly larger than first imagined. It may also be that many authors will meet each other for the first time on these pages and realize that they are working on a common topology. The number of applications suggested in the patent literature is large and growing. Included are impact-resistant plastics, ion exchange resins, noise-damping materials, a type of thermoplastic elastomer, and many more.

This book describes the Conference on Fire and Smoke-Resistant Materials held at the National Academy of Sciences on November 8-10, 1994.
