Abstract: A propylene polymer composition composed of a propylene polymer (A1) produced by using a metallocene catalyst and having a melt flow rate (MFR) of 0.01-30 g/10 min, a propylene polymer (A2) having an MFR of 30-1,000 g/10 min and, if necessary, a flexible polymer, wherein the ratio of the MFR of the polymer (A2) to that of the polymer (A1) is at least 30. A propylene polymer composition composed of a propylene polymer produced by using a titanium catalyst and having an MFR of 0.01-30 g/10 min, the above polymer (A2) and, if necessary, a flexible polymer. A propylene polymer composition composed of a propylene polymer produced by using a titanium catalyst and having an MFR of 0.01-50 g/10 min and an ethylene-olefin random copolymer produced by using a metallocene catalyst. A propylene polymer composition composed of a propylene polymer produced by using a catalyst containing a specified metallocene compound and at least one synthetic resin selected from among a propylene polymer other than the above propylene polymer, an olefin elastomer and an olefin polymer. All of the above polymer compositions are excellent in heat resistance, mechanical strengths and tensile elongation at break and are suitable for producing various structural materials of automobiles, household electric appliances, etc., daily necessities, films, sheets, and so forth.
