Abstract
A novel terminally functional (i.e., telechelic) polymers having a polyisobutylene are described. The end groups are styryl and can be reacted with conventional monomers to form copolymers having unique physical properties. Copolymerizations with N-vinyl-2-pyrrolidone produce amphiphilic polymers which are useful in the areas of medicine and agricultural chemicals.
