Abstract
Block copolymers are made by polymerizing propylene or a mixture thereof with ethylene containing 1.5 to 5 mol. per cent of the latter in an inert solvent with catalyst system consisting of an aluminium alkyl dihalide, titanium trichloride and an alkoxysilane, the mol ratio of aluminium alkyl dihalide and titanium trichloride being in the range of 0.2:1 to 10:1 and the atomic ratio of aluminium to active silane oxygen being in the range of 5:4 to 10:1, then discontinuing the monomer feed and continuing polymerization with a second feed which is ethylene or a mixture thereof with a lesser quantity of propylene than is present in the first feed, and recovering a product having an ethylene content of 3 to 20 mol. per cent. The alternation of feeds may take place more than once. Silanes specified are trimethylethoxysilane, diethyldiethoxysilane, tetramethoxysilane and ethyl orthosilicate.
