A polymer-supported constituent for olefin polymerization catalyst obtained by: mixing in organic solution a chlorine-containing organic polymer and a magnesium compound, removing the solvent, and reacting the resulting magnesium-modified polymer with a titanium halide. An olefin polymerization catalyst is formed by mixing such a polymer-supported constituent with an appropriate organo-metallic compound and optionally also an appropriate selectivity control agent.
