    Abstract: A process for producing a propylene polymer composition by conducting a multi-stage polymerization comprising the step (a) of producing a propylene (co)polymer (a) and the step (b) of producing an ethylene copolymer (b) in an arbitrary order in the presence of a transition metal compound (A) containing a ligand having a cyclopentadienyl skeleton and a compound (B) capable of activating the compound (A) and also in the presence, in the step (b), of the polymer produced in the preceding step (a), in which process the obtained polymer composition contains 20-90 wt. % of the (co)polymer (a) and 80-10 wt. % of the copolymer (b) and has a melt flow rate of 0.01-500 g/10 min as measured at a temperature of 230 °C under a load of 2.16 kg. This process can provide a propylene polymer composition having an excellent balance among rigidity, heat resistance and impact resistance.

    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.
