Abstract
A propylene polymer composition comprising a propylene polymer prepared by using a zirconocene catalyst having two aryl-substituted indenyl group and having a melt flow rate (MFR) of 0.01 to 30 g/10 min and a second propylene polymer prepared by using a zirconocene catalyst having a melt flow rate (MFR) of 30 to 1,000 g/10 min and, if desired, a soft polymer, a ratio of the MFR of the second propylene polymer to the MFR of the second propylene polymer being not less than 30. These propylene polymer compositions are excellent in heat resistance, mechanical strength, tensile elongation at break, etc., and hence they can be favorably used for various structural materials such as those of automobile and electrical appliances, daily necessaries, various films and sheets.
