摘要：Catalyst compositions exhibiting high activity for the polymerization of a-olefinsare prepared by reacting (A) tetravalent or trivalent titanium compounds such as atitanium tetraalkoxide, (B) an anhydrous nickel compound such as nickel chloride, (C) anorganomagnesium component such as a hydrocarbon soluble complex of dialkylmagnesium and an alkyl aluminum, (D) a halide source such as a hydrogen halide or analkyl aluminum halide, and (E) an alkyl aluminum halide if not otherwise provided.Polymerization processes employing this catalyst composition do not require
subsequent catalyst removal steps and the resulting polymers have broader molecularweight distributions than do corresponding polymers prepared without the addedanhydrous nickel compound.
