    • A solid catalyst component for polymerization of olefins prepared by reacting a titanium halide, a diester of aromatic dicarboxylic acid and a dialkoxymagnesium having a bulk density of at least 0.25 g/ml and an average particle size of 1 to 100 .mu.m. The average rate of temperature rise from the temperature at which the titanium halide is allowed to come in contact with the dialkoxymagnesium to the temperature at which the reaction is initiated is in a range of from 0.5 to 20.degree. C./min. Such catalyst can further comprise an organic aluminum compound and an organic silicon compound. The use of said catalyst makes it possible to efficiently obtain a polyolefin having a high stereoregularity, a high bulk density and excellent particle properties.
