Abstract

A novel polyisobutylene-based diol has been synthesized and subsequently used in conjunction with tolylene diisocyanate (TDl) to yield polyurethanes. The diol was obtained by quantitative hydroboration/oxidation from the corresponding telechelic diolefin which in turn was prepared by quantitative dehydrochloration of the corresponding dichloride. The products are strong rubbers exhibiting rapid recovery upon releasing the strain of stretching. The Tg's of polyurethanes prepared in the absence and presence of 1,4-butanediol extender have been determined.
