Summary

Polyisobutylenes carrying one or two terminal isopropenyl unsaturations have been obtained by complete dehydrochlorination of α-tert. -butyl-ω-tert. chloropolyisobutylene and α, ω-di(tert.-chloro) polyisobutylene, respectively. By the use of t-BuOK in refluxing THF only 1-olefin formed leading to a new macromer and a symmetrical telechelic diolefin. According to H1 NMR spectroscopy the structure of this new telechelic polymer is:
