MANUFACTURE OF POLYMERIZATION CATALYST AND MANUFACTURE OF ETHYLENE POLYMER THEREWITH

Document Type and Number:

Japanese Patent JPS5837010

Kind Code:

A

Abstract:

This invention relates to a process for forming a catalyst containing chromium and vanadium, by depositing chromium- and vanadium compounds on an inert, particulate inorganic support. The chromium is deposited as a complex of a chromium compound that may be a chromium-1,3-diketocompound with a Group II or III element hydrocarbyl. The vanadium compound can be but need not be a complex of a vanadium compound with a Group II or III element. Not more than one of the chromium- and a vanadium compounds may be the chelate of a 1.3-diketo-compound, whether or not complexed with a Group II or III element hydrocarbyl. The process for polymerizing an olefin using the catalysts of the invention is also disclosed.
