Abstract
A catalyst polymerization system comprises (a) 1 part by weight of the solid reaction product of TiCl4 with an alkylaluminium compound containing chlorine, (b) 0.1 to 1 part by weight of the solid reaction product of TiCl4 with aluminium, and (c) diethylaluminium monochloride. The catalyst is used for making olefine polymers having a broad molecular weight distribution by polymerizing in an inert diluent, ethylene, or copolymerizing ethylene with up to 5% by weight of butene-1, or propylene, in the presence of hydrogen, by low-presssure techniques. The polymers besides having a broad molecular weight distribution, have a U-value within the range of from 10 to 18 at a reduced specific viscosity of 2.7, determined in a 0.1% by weight solution in xylene at 110 DEG C.
