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. A.W. K.S.L.
