ABSTRACT:
In the polymerization of 1-olefins using a solid catalyst component composed of a titanium trichloride and an activator component composed of a trialkylaluminum, the stereospecificity of the catalyst is increased by replacing a portion of the trialkylaluminum in the activator component with a dialkylaluminum dialkylphosphate.
