Abstract
1447916 Titanium halide polymerization catalyst TOHO TITANIUM CO Ltd 5 June 1974 [5 June 1973] 24897/74 Heading C3P Alpha olefins are polymerized in the presence of (a) an organoaluminium compound and (b) a titanium halide component obtained by milling (i) a titanium halide in a valency below 4, (ii) and alpha, betaunsaturated carboxylic acid ester and (iii) a silicon compound which is an organosilane or a polysiloxane. Optionally, oxygen may be present. Examples refer to the homopolymerization of propylene or block copolymerization (propylene-b-ethylene-co-propylene) in solution or in a fluidized bed of polypropylene using catalysts typically comprising (a) Et 2 AlCl and (b) the product of milling (i) TiCl 3 .1/3AlCl 3 , (ii) methyl methacrylate, methyl crotonate, methyl cinnamate, or diethyl maleate, and (iii) dimethyl polysiloxane, methyl chloropolysiloxane and tetraethylsilicate, and in some eases in the presence of oxygen or hydrogen.
