Abstract: 1301399 Polymerization catalyst SOLVAY & CIE 16 Dec 1970 [17ÀDec 1969] 59712/70 Heading C3P A Ziegler-Natta type catalyst is prepared by reducing liquid TiCl 4 , TiBr 4 or VCl 4 with a liquid organometallic compound of a metal of Groups I to III in the presence of a porous inert support, separating and (if required) heating the product, then activating the resulting supported reduced halide with an organometallic compound of a metal of Groups I to III. The reduction is carried out by first impregnating the support with one reatant then adding it to the second reactant which is in the form of a pure liquid or a solution, the non-supported reactant being used in excess if it is a pure liquid and either in excess or in the stoichiometric proportion if it is in solution. The use of Al 2 O 3 , TiO 2 and MgO as support materials is described; the supports are in the form of rounded bodies of diameter 50-250 Á composed of agglomerated particles, the individual particles having diameter 0À2-2 Á. Bulk polymerization of propylene and copolymerization of ethylene and propylene in liquid propylene are described, using catalysts derived from TiCl 4 , reduced with Et 3 Al, (i-Bu) 3 Al or Et 2 AlCl and activated with Et 2 AlCl.
