Abstract
Linear high polymers of ethylene are prepared in granular form by polymerization in the presence of a hydrocarbon solvent and a catalyst prepared by precipitating a halide of a metal of Group IV(a), V(a) or VI(a) of the Periodic Table with an alkyl compound of a metal of Group II or III of said Table on to an inert supporting material comprising an ethylenically unsaturated hydrocarbon polymer, the ratio of support to solvent being one part by weight to 10-50 parts by volume, and that of support to catalyst being between 1:2 and 1:0,25 by weight. The supporting material may be polyethylene, polypropylene or polystyrene. The preferred catalyst components are titanium tetrachloride and ethyl aluminium sesquichloride, and the preferred solvent is heptane. The catalyst components may be added simultaneously or in succession to a suspension of the supporting material in the solvent, and the resulting mixture aged.
