Book Description
The sheer volume of topics which could have been included under our general title prompted us to make some rather arbitrary decisions about content. Modification by irradiation is not included because the activity in this area is being treated elsewhere. We have chosen to emphasize chemical routes to modification and have striven to pre sent as balanced a representation of current activity as time and page count permit. Industrial applications, both real and potential, are included. Where appropriate, we have encouraged the contributors to include review material to help provide the reader with adequate context. The initial chapter is a review from a historical perspective of polymer modification and contains an extensive bibliography. The remainder of the book is divided into four general areas: Reactions and Preparation of Copolymers Reactions and Preparation of Block and Graft Copolymers Modification Through Condensation Reactions Applications The chemical modification of homopolymers such as polyvinylchlo ride, polyethylene, poly(chloroalkylene sulfides), polysulfones, poly chloromethylstyrene, polyisobutylene, polysodium acrylate, polyvinyl alcohol, polyvinyl chloroformate, sulfonated polystyrene; block and graft copolymers such as poly(styrene-block-ethylene-co-butylene block-styrene), poly(I,4-polybutadiene-block ethylene oxide), star chlorine-telechelic polyisobutylene, poly(isobutylene-co-2,3-dimethyl- 1,3-butadiene), poly(styrene-co-N-butylmethacrylate); cellulose, dex tran and inulin, is described.

Book Description
Modification of Polymer Properties provides, for the first time, in one title, the latest information on gradient IPNs and gradient copolymers. The book covers the broad range of polymer modification routes in a fresh, current view representing a timely addition to the technical literature of this important area. Historically, blends, copolymers, or filled polymers have been developed to meet specific properties, or to optimize the cost/properties relationship. Using the gradient structure approach with conventional radical polymerization, it has been shown that it is possible to optimize properties if appropriate gradients in the composition of copolymer chains are obtained. An overview of the gradient structure approach for designing polymers has not appeared in the recent literature and this title covers the different methods used to modify properties, offering the whole range of ways to modify polymers in just one volume and making this an attractive option for a wide audience of practitioners. The approach for each chapter is to explain the fundamental principles of preparation, cover properties modification, describe future research and applications as examples of materials that may be prepared for specific applications, or that are already in use, in present day applications. The book is for readers that have a basic background in polymer science, as well as those interested in the different ways to combine or modify polymer properties. Provides an integrated view on how to modify polymer properties Presents the entire panorama of polymer properties modification in one reference, covering the essential information in each topic Includes the optimization of properties using gradients in polymers composition or structure

Book Description
Modified Polymers, Their Preparation and Properties brings together the main lectures presented at the Fourth Bratislava Conference on Polymers held in Bratislava, Czechoslovakia, on July 1-4, 1975. Contributors explore the properties of modified polymers and their preparation, covering topics ranging from radiation crosslinking of polyvinyl chloride (PVC) with ethylene glycol dimethacrylate to chemical modification of polymers and the influence of chemical structure on the properties of polymers. This book is comprised of eight chapters and begins with a discussion on crosslinking of PVC in the presence of ethylene glycol dimethacrylate, studied by microcalorimetry, electron spin resonance, and structure investigation. The next chapter examines some characteristic features of chemical transformations of polymers on three examples: reactions of various organo-lithium bases onto the ester carbonyls of polymethylmethacrylate (PMMA); reaction of phenyl-lithium onto the carbonyl groups of PMMA; and chemical modification of polyvinylalcohol by metallation and subsequent reactions of alkylhalides or of propane sulfone. Subsequent chapters focus on how chemical structure affects polymer properties; alternating copolymer graft copolymers; acrylonitrile block and graft copolymers; and problems of polymer modification and the reactivity of functional groups of macromolecules. The final chapter is devoted to the separation and characterization of block and graft copolymers by thin-layer chromatography. This monograph will be a valuable source of information for chemists.

Book Description
Properties of Polymers: Their Correlation with Chemical Structure; Their Numerical Estimation and Prediction from Additive Group Contributions summarizes the latest developments regarding polymers, their properties in relation to chemical structure, and methods for estimating and predicting numerical properties from chemical structure. In particular, it examines polymer electrical properties, magnetic properties, and mechanical properties, as well as their crystallization and environmental behavior and failure. The rheological properties of polymer melts and polymer solutions are also considered. Organized into seven parts encompassing 27 chapters, this book begins with an overview of polymer science and engineering, including the typology of polymers and their properties. It then turns to a discussion of thermophysical properties, from transition temperatures to volumetric and calorimetric properties, along with the cohesive aspects and conformation statistics. It also introduces the reader to the behavior of polymers in electromagnetic and mechanical fields of force. The book covers the quantities that influence the transport of heat, momentum, and matter, particularly heat conductivity, viscosity, and diffusivity; properties that control the chemical stability and breakdown of polymers; and polymer properties as an integral concept, with emphasis on processing and product properties. Readers will find tables that give valuable (numerical) data on polymers and include a survey of the group contributions (increments) of almost every additive function considered. This book is a valuable resource for anyone working on practical problems in the field of polymers, including organic chemists, chemical engineers, polymer processers, polymer technologists, and both graduate and PhD students.

Book Description
This book chronicles the proceedings of the Second International Symposium on Polymer Surface Modification: Relevance to Adhesion held Newark, New Jersey, May 24--26, 1999. Polymeric materials are intrinsically not very adhesionable and this necessitates their surface treatment to enhance their adhesion characteristics to other materials. Since the first symposium on this topic, held in 1993, there has been a tremendous R&D activity in devising novel or ameliorating the existing techniques for surface modification of polymers. This volume contains a total of 32 papers, which have been rigorously peer-reviewed and suitably revised before inclusion in this volume. The book is divided into three parts as follows. Part 1: Plasma Surface Modification Techniques; Part 2: Other/Miscellaneous Surface Modification Techniques; and Part 3: General Papers. The topics covered include: plasma surface modification of a variety of polymers using various plasma gases; atmospheric plasma system; surface functionalization; ultrahydrophobic polymeric surfaces; metallization of plasma treated polymers; surface modification of polymers via molecular design for adhesion promotion; wet chemical methods for polymer surface modification; laser surface modification of various polymers; UV/ozone treatment; surface and interface studies of treated polymer surfaces by an array of techniques; bioadhesion of polymeric biomaterials to tissue; polymer-fiber systems; and plasma deposited coatings.
