Title: Supported high efficiency polyolefin catalyst component and methods of making and using the same

Patent ·
OSTI ID:5043931

A process is described for the polymerization of olefins. In this process, an alpha-olefin or a mixture of alpha-olefins under suitable reaction conditions is contacted with a catalyst system comprising a catalyst and a cocatalyst. The cocatalyst comprises an organometallic compound and the catalyst comprises a solid resulting from the interaction of reactants consisting essentially of a support base selected from magnesium and manganese dihalides. A second solid material is selected from aluminum trihalides, phosphorus trichloride, and phosphorus oxyrichloride. A first electron donor is selected from ethers and non-halogenated esters of carboxylic acids. The catalyst is prepared by co-comminuting the support base and the second solid material to form an anhydrous mixture, co-comminuting the anhydrous mixture with the first electron donor to form a catalyst support, and treating the catalyst support with, the transition metal compound.
