Abstract
Ethylene polymerization catalysts are prepared by depositing a chromocene compound on a support with a titanium compound and activating the final blend at 300.degree. C. to about 1000.degree. C. A fluoriding agent can be optionally added where a narrower molecular weight distribution of the polyethylene to be obtained is desired. Catalysts with good reproducibility, when prepared by this method, show particular utility in production of polyethylene by a fluid bed process.
