Abstract
Procedure for the manufacture of homopolymers and mixed polymers of ethylene; - with a molecular weight of more than 500,000, in which the regulation of the molecular step is carried out by the addition of alcohols, within an inert dispersing medium, at 30 to 130ºC., and 1 to 100 bars in the presence of catalysts that have been obtained: by transformation of titanium (IV) halide with an organo-aluminum combination, separation of the titanium (III) halide, thus formed, from the reaction medium and washing with an inert dispersing medium; and by the activation, carried out next, with an organ-aluminum combination, so that the ratio of atoms between titanium and aluminum is from 1: 0.1 to 1: 2.0 characterized in that the catalysts are treated at 0 to 80ºC with 0.05 to 50 grs. of an α-olefin with 2 to 6 carbon atoms, or mixtures of these olefins, for every gram of titanium (III) halide.
