Heteropolyacid catalyzed polymerization of olefins |
| 摘要 |
Phosphotungstic acid salts are used to polymerize C2-C30 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 +E,ovs Mn+EE 300-20,000 polymer.
