High efficiency catalyst for polymerizing olefins |
| abstract |
Compositions exhibiting high catalytic activity in the polymerization of alpha -olefins, particularly higher olefins, are prepared by reacting (A) tetravalent titanium compounds such as titanium tetraalkoxide, (B) an organoaluminum compound, (C) an organomagnesium component such as a hydrocarbon soluble complex of dialkyl magnesium and an organo aluminum compound such as triethyl aluminum and, (D) as a halide source, a tetravalent tin compound such as tin tetrachloride. Polymerization processes employing this catalyst composition do not require conventional catalyst removal steps in order to provide polymers having suitable color and other physical characteristics and these catalysts provide higher efficiencies than those catalysts employing HCl as the halide source. |
