ABSTRACT:
A process is described herein for improving the crystalline olefin polymerization yield and soluble polymer production of a high surface area, large porosity, brown catalyst component comprising beta titanium trichloride and some of at least one organic electron pair donor compound, which component is prepared by organoaluminum compound reduction of titanium tetrachloride followed by incorporation of the reduced solid with said donor compound and thereafter treatment with an electron pair acceptor compound. The improved process employs in the reduction a dialkylaluminum compound and a second material, which second material is subsequently substantially extracted prior to use of said component for polymerization.
