ABSTRACT:
Compositions exhibiting high catalytic activity in the polymerization of .alpha.-olefins at temperatures above 140.degree. C. are provided by reacting a transition metal compound such as tetra(isopropoxy)titanium, an organomagnesium component such as a hydrocarbon soluble complex of dialkyl magnesium and an alkyl aluminum, e.g., di-n-butylmagnesium.x triethylaluminum and a hydrogen halide or an active hydrocarbyl halide such as t-butyl chloride. 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.
