ABSTRACT:
A process for preparation of a component of a catalyst for polymerization of .alpha.-olefins is disclosed. The process comprises the steps of heating a titanium containing component during and/or after milling operation thereof. The titanium-containing catalyst component thus produced makes it possible to produce polymers having a high stereoregularity in high specific yield.
