Abstract

1,264,393. Polymerization of olefins. UNION CARBIDE CORP. 9 Oct., 1969 [14 Oct., 1968], No. 49711/69. Heading C3P. Olefins are polymerized by contact with a catalyst comprising a #-arenechromium tricarbonyl adsorbed on an inorganic oxide support having a high surface area, at a temperature and pressure sufficient to initiate the polymerization under an atmosphere free of moisture and oxygen. The preferred catalysts are #-benzene chromium tricarbonyl and #-mesitylene chromium tricarbonyl adsorbed on silica, silicaalumina, thoria or zirconia. An organoaluminium compound may also be present. The examples relate to the preparation of polyethylene.
