Abstract
A catalyst for the polymerization of olefins which exhibits a high catalytic activity and is capable of producing a stereoregular polymer in a high yield. The catalyst includes a catalyst component for the polymerization of olefins prepared by subjecting a solid composition obtained by a process comprising contacting dialkoxymagnesium, diester of aromatic dicarboxylic acid, aromatic hydrocarbon and titanium halide to a heat treatment in the presence or absence of a solvent; a silicon compound; and an organic aluminum compound.
