Process For Preparing Blends Of Cis-1,4-Polybutadiene And Syndiotactic 1,2-Polybutadiene |
| 摘要 |
A process for preparing a blend of cis-1,4-polybutadiene and syndiotactic 1,2 polybutadiene, the process comprising the steps of (i) polymerizing 1,3-butadiene in the presence of a lanthanide-based catalyst to form a polymerization mixture including cis-1,4-polybutadiene, and (ii) polymerizing 1,3-butadiene in the presence of a cobalt-based catalyst within the polymerization mixture including cis-1,4-polybutadiene to form syndiotactic 1,2-polybutadiene and thereby produce a blend of cis-1,4-polybutadiene and syndiotactic 1,2-polybutadiene. |
