Summary:PURPOSE:To obtain crystalline polypropylene resin composition, containing a polymer prepared by anionic polymerization of cyclohexyl methacrylate and capable of providing molded products excellent in physical properties. CONSTITUTION:A crystalline polypropylene resin composition containing (A) crystalline polypropylene, e.g., random or block copolymer, prepared by polymerizing propylene with <=50wt.% other olefins in the presence of a catalyst system consisting of titanium trichloride (modified substance) obtained by reducing titanium tetrachloride with metallic aluminum, hydrogen, etc., an organoaluminum compound and a stereoregularity improver (e.g., ether or ester) and (B) >=0.01wt.ppm, preferably 0.1-1000wt.ppm polymer, prepared by anionic polymerization of cyclohexyl methacrylate and having 1000-10000000 number- average molecular weight.
