The purpose of this book is to improve understanding of the chemical nature of the
global rubber industry in a context of commercial and political forces. These forces
have often resulted in higher prices and periodic shortages in the supply of raw
materials and intermediates necessary for the continued production of rubber
products. Both the 20th and 21st centuries have witnessed numerous raw material
shortages that have seriously impacted the global rubber industry. In all probability,
these shortages and disruptions will continue for the foreseeable future.
