| abstract | 1473048 Polymerization of olefins MITSUBISHI CHEMICAL INDUSTRIES Ltd 19 June 1975 [27 June 1974] 26177/75 Heading C3P Olefins are homopolymerized or copolymerized in the absence of water or oxygen and in the presence of a catalyst comprising (A) a solid component prepared by treating a mixture of a titanium tetrahalide, a vanadyl trihalide and a vanadyl alcoholate with an organoaluminium compound and (B) an organoaluminium compound. The transition metal compounds are preferably mixed then treated with the organoaluminium compound in an inert atmosphere in a hydrocarbon diluent. In the examples titanium tetrachloride, vanadyl chloride and tri-n-butoxy vanadyl are mixed in benzene, heated then treated with ethylaluminium sesquichloride or ethyl aluminium dichloride and the solid is separated from the medium to form component A which is used with triethylaluminium, triisobutyl aluminium or diethylaluminium ethoxide to polymerize ethylene or a mixture of ethylene and propylene in n-hexane in the presence of hydrogen. In comparative examples one of the vanadium compounds is omitted. |
