ABSTRACT:
Disclosed is a method for preparing polyolefins containing vinylidine end groups from quasiliving carbocationically terminated polyolefin polymers by contacting the quasiliving carbocationically terminated polymer with quenching agent selected from the group consisting of polypyrrole, polyvinylpyridine, polyphenothiazine, polyoxazine, and polypyrrole-co-thiophene and substituted derivatives thereof.
