In this second edition, considering the increasing social concerns on sustainability, the authors newly introduce an ingenious material design of rubber vulcanization along with outlining the reaction mechanism. Novel characterization methods for rubber networks and filler structures are updated, and the unique feature of rubber tires for modern and future sustainable society is described. The contents of this book are of interest even for general readers who are concerned with environmental and sustainable issues on our Earth. This book also provides an up-to-date text on rubber science and is a breakthrough among many rubber-related publications. Emphasis is placed on the most modern scientific approaches to rubber science, departing from the usual detailed descriptions of trial-and-error results of traditional rubber technology. This book is a good introduction to modern rubber science both for graduate students and for more or less experienced rubber engineers for updatingtheir way of thinking in handling of technological problems.
