Abstract
A cocatalyst for use in association with a catalytic component comprising a titanium compound and an internal electron donor on a magnesium halide support for the polymerization of propylene alone or propylene with ethylene or a C.sub.4 to C.sub.12 alpha-olefin, said cocatalyst consisting essentially of an organic aluminum compound and an external electron donor consisting essentially of a non-aromatic silane with two Si--O--C bonds and a monoether and/or a silane with a single Si--O--C bond and the resultant catalyst wherein such cocatalyst is combined with a catalytic component known for use in polymerizing propylene.
