Chemistry Technology And Properties Of Synthetic Rubber

The manual is intended for the 5th year students of the Polymer Faculty of 020015 «Chemical Technology» course. The manual reflects the current state of the elastomers science and production technologies. The focus is on technological methods, based on the scientific understanding of the chemistry in the synthesis of general-purpose and special rubbers, their properties and applications.The content of the manual corresponds to the program of the course «Technology of Elastomers». Published by the decision of the Editing and Publishing Board of Kazan National Research Technological University

This book has its origin in a proposal made a few years ago that I should collaborate with Dr H. J. Stern in the production of a third edition of his well-known text-book entitled Rubber: Natural and Synthetic. The sugges tion was that I should contribute a series of chapters on synthetic rubbers. Although, in the event, it has not proved possible to publish the full book in the form originally planned, it was apparent that, with some restructuring, the material which I had collected would be valuable as an independent summary of the chemistry and technology of synthetic rubbers. It is in this form that the material is now offered. The primary purpose of this book is to provide a brief up-to-date survey of the principal types of synthetic rubber which have been and are currently available. Two classes of material are included which are regarded by some as being thermoplastics rather than rubbers, namely, plasticised polyvinyl chloride and the thermoplastic synthetic rubbers. The topics which are covered for each main family of synthetic rubbers are (i) the sources of the monomers, (ii) polymerisation procedures and the effects of important polymerisation variables upon the rubber produced, (iii) the types of rubber currently available commercially, (iv) interesting aspects of the compounding of the rubbers, with special reference to such matters as vulcanisation, reinforcement, protection against degradation, and (where appropriate) plasticisation, and (v) an indication of applications.

This book is intended for those people who have a knowledge or understanding of rubber materials and processes but who wish to update their knowledge. It should be read in conjunction with Developments in Rubber Technology-l as that volume discussed developments in natural rubber and selected special purpose synthetic rubbers as well as additives. The authors have been selected for their expertise in each particular field and we, as editors, would like to express our appreciation to the individual authors and also to their companies. Such a book would be impossible to produce without such active cooperation as we have received. Volumes 1 and 2 of Developments in Rubber Technology cover rubbers which are processed and vulcanised in the traditional manner. It is appreciated that the omission of non-vulcanised rubber materials (the so called thermoplastic elastomers) will be unwelcome to many readers but it is intended, because of the size of the subject, to cover these materials in a subsequent volume.

Science and Technology of Rubber, Second Edition provides a general survey of elastomers and an examination of rubberlike elasticity, with an emphasis on a unified treatment ranging from physical theory to final applications. Researchers in polymer science and engineering fields will find coverage of recent advances, unsolved problems and projections, and processing. Expanded coverage Updated chapters featuring substantially more information A unified treatment of the subject, with comprehensive coverage ranging from chemical aspects such as elastomer synthesis and curing, through theoretical developments and characterization of equilibrium and dynamic properties, to final applications

About ten years after the publication of the Second Edition (1973), it became apparent that it was time for an up-date of this book. This was especially true in this case, since the subject matter has traditionally dealt mainly with the structure, properties, and technology of the various elastomers used in industry, and these are bound to undergo significant changes over the period of a decade. In revising the contents of this volume, it was thought best to keep the orig inal format. Hence the first five chapters discuss the same general subject matter as before. The chapters dealing with natural rubber and the synthetic elastomers are up-dated, and an entirely new chapter has been added on the thermoplastic elastomers, which have, of course, grown tremendously in importance. Another innovation is the addition of a new chapter, "Miscellaneous Elastomers," to take care of "old" elastomers, e.g., polysulfides, which have decreased some what in importance, as well as to introduce some of the newly-developed syn thetic rubbers which have not yet reached high production levels. The editor wishes to express his sincere appreciation to all the contributors, without whose close cooperation this task would have been impossible. He would especially like to acknowledge the invaluable assistance of Dr. Howard Stephens in the planning of this book, and for his suggestion of suitable authors.

Elastomers and Rubber Compounding Materials reviews the properties of elastomers and particular groups of ingredients and chemicals mixed into the basic elastomer to form a rubber compound. After introducing the history of rubber industry and the general properties of rubber, the book discusses the properties, classification, concentration, stabilization, modification, application, transport, and storage of latex. It presents as well the methods of production, composition, physical properties, and chemical reactions of dry rubber. The book then focuses on the production and classification of different synthetic rubbers, such as styrene-butadiene, isoprene, butadiene, ethylene-propylene, and chloroprene. It also discusses the production, properties, and applications of elastomers, vulcanization chemicals, fillers, stabilizers, plasticizers, blowing agents, and textile reinforcing materials used in formulating rubber compounds. This book will be of great value not only to those who are in the rubber industry, but also to students of polymer science and rubber technology.

Science and Technology of Rubber covers the most important aspects of rubber science and technology, from synthesis and structure to elasticity and flow, blending, filling, and cross-linking. Polymerization and copolymerization, the rheological behavior of unvulcanized rubber, vulcanization, reinforcement of elastomers by particulate fillers, and the chemical modification of polymers are also discussed. This book is comprised of 14 chapters; the first ten of which take the reader from an introduction through synthesis characterization, mechanical behavior, and flow to the major processing steps of filling, compounding, and vulcanization and to the theories and measurement of elastomeric performance, leaning strongly on the ""materials"" approach. The next three chapters deal with blended, modified, and thermoplastic elastomers, touching on topics such as polymer esterification, etherification, hydrolysis, and hydrogenation as well as the influence of blending on the properties of elastomer/plastic blends, especially impact strength and crack resistance. The book concludes with a chapter on tire manufacture and engineering, with emphasis on the geometric, structural, and chemical aspects of tire. This book will be of vital interest to students, practitioners, and research and development managers, as well as to anyone interested in the unusual chemistry and physics and the outstanding properties and usefulness of elastomers.
