ABSTRACT Compositions exhibiting high catalytic activity in the polymerization of .alpha.-olefins are provided by react- ing an ester of titanium, a so-called titanate such as tetra(isopropxy)titanium, a hydrocarbon soluble organo- magnesium compound or complex such as a complex of dialkyl magnesium and an alkyl aluminum, e.g., di-n-butylmagnesium?- 1/6 triethylaminum and an alkyl aluminum halide. Poly- merization processes employing this catalyst composition do not require conventional catalyst removal steps in order to provide polymers having suitable color and other physical characteristics.
