Process for copolymerizing conjugated dienes and alpha-olefins |
| abstract |
Conjugated dienes and olefins, such as butadiene and propylene, are copolymerized by a catalyst system comprising a metal component, TiClnBr4 n or VClmBr5 m, a reducing agent of the formula AlR3 wherein R is hydrogen or a hydrocarbon group, and an organic sulfoxide such as diphenyl sulfoxide. The use of the organic sulfoxide modifier allows the use of higher and more practical temperatures to obtain desirable molecular weights, yields and microstructure than the prior art related copolymerizations which require much lower and less practical polymerization temperatures to obtain corresponding results. |
