Abstract
1518400 Polymerization of ethylene RUHRCHEMIE AG 1 Dec 1976 [6 Dec 1975] 51057/76 Heading C3P A (co-) polymer of ethylene having a molecular weight above 500,000 is prepared by polymerizing ethylene in an inert diluent in the presence of an alcohol and a catalyst prepared by reducing a Ti IV halide with an organoaluminium compound to form a Ti III halide which is subsequently activated with an organoaluminium compound with a Ti to Al ratio in the range 1 : 0À1 to 1 : 2 then treated at 0 to 80‹ C. with 0À05 to 50 gm. of one or more C2-6 alpha-olefines per gm. of Ti III halide. In the examples ethylene is continuously homopolymerized or copolymerized with butene-1 in an aromatic hydrocarbon in the presence of n-butanol and the product of reducing TiCl4 with Et2AlCl, activating the resulting TiCl3 with Et2AlCl and contacting it with ethylene or butene-1.
