ABSTRACT:
Phosphotungstic acid salts are used to polymerize C.sub.2 -C.sub.30 .alpha.-olefins and derivatives thereof to form highly reactive products having a high content of terminal vinylidene groups and .beta.-isomers in resonance therewith. Isobutylene has been polymerized to form a Mn 300-20,000 polymer.
