Catalyst component comprising brown titanium trichloride

Abstract From the Canadian patent

A new catalyst component and its use with an organoaluminum compound which component is a brown solid of high surface area and large pore volume consisting essentially of beta titanium trichloride and a small amount of an organic electron pair donor compound. This solid when used in conjunction with an organoaluminum compound to polymerize alpha-olefins produces product polymer at substantially increased rates and yields compared to present commercial, purple titanium trichloride while coproducing reduced amounts of low-molecular-weight and particularly, amorphous polymer. Combinations of this new catalyst component and an organoaluminum compound can be further improved in their catalytic …
