The Rubber Division of the American Chemical society was founded to promote the education, professional growth, and betterment of those individuals associated with the rubber and associated industries. In 2009, the 100th anniversary of the division will be marked. Over those ten decades, the elastomeric profession has undergone innovations, improvements, re-tooling, and re-thinking. This book traces the history of the division and details how it became the forum for the many people who ultimately impacted the advances in the rubber industry. Started by twenty-eight rubber chemists in the early 1900s, the Rubber Division has grown substantially. Its story reflects how people of simple backgrounds, working together, have propelled advances in natural and synthetic rubber materials and applications, polymer engineering and manufacturing, thermoplastics research, and chemistry. The Rubber Mirror reveals the heart and spirit of individuals. Their chronicles are primary documents in the history of the Rubber Division.
