  • Developed out of necessity, as a war-born material, butyl rubber and its derivatives became one of the most important man made materials for the progress of modern civilization, especially for the tire industry. The automobile industry as we know it today is wholly dependent upon polyisobutylene-based elastomers primarily due to air-retention characteristics which contribute significantly to the safety, extended life, convenience, and comfort provided by tires. Although the early inventions in the field of isobutylene polymerization were empirical and early commercial introductions were based on thorough trial-and-error optimizations, the understanding of Staudinger’s concept of ‘Uber Polymerization’ and the acceptance of the macromolecular hypothesis paved the way for the design and development of tailored, high value-in-use elastomers of technological importance in this field. This paper will present the key inventions and commercial developments that changed ‘futile-butyl’ into technologically important elastomers of the last century as well as the challenges and potential for these elastomers for the future of an energy transition economy.
