ABSTRACT:
The invention encompasses the synthesis of telechelic, i.e., terminally functional, macromolecular monomers (macromers) and their subsequent homo- and copolymerization. The macromers produced are asymmetric, having dissimilar head and tail groups which provide independent reaction sites. Macromers include .alpha.-phenyl-.omega.-t-chloropolyisobutylene, which can be reacted to form poly(methyl methacrylate-g-isobutylene). The graft copolymers provide novel physical properties which are the product of the respective grafts.
