| abstract |
A process of forming a polyolefin catalyst component includes contacting a metal compound of the formula MR2 with a diketone to form a metal bis(diketonate) having the formula M(OCRCR'CRO)2, wherein M is a Group IIA or Group VIIB metal, and wherein R and R' are each hydrocarbyls or substituted hydrocarbyls having from 1 to 20 carbons atoms. Catalyst components, catalysts, polyolefin polymers, catalysts systems, and methods of preparing same are disclosed. |
