Propylene polymer compositions |
摘要 |
<p>A propylene polymer composition comprises a propylene polymer (A1) prepared by using a metallocene catalyst and having a melt flow rate (MFR) of 0.01 to 30 g/10 min and a propylene polymer (A2) prepared by using a metallocene catalyst and having a melt flow rate (MFR) of 30 to 1,000 g/10 min and, if desired, a soft polymer, a ratio Ä(A2)/(A1)Ü of the MFR of said propylene polymer (A2) to the MFR of said propylene polymer (A1) being not less than 30. A propylene polymer composition comprising a propylene polymer prepared by using a titanium catalyst and having MFR of 0.01 to 30 g/10 min and the above-mentioned propylene polymer (A2) and, if desired, a soft polymer. A propylene polymer composition comprising a propylene polymer prepared by using a titanium catalyst and having MFR of 0.01 to 50 g/10 min and an ethylene/olefin random copolymer prepared by using a metallocene catalyst. A propylene polymer composition comprising a propylene polymer prepared by using a catalyst containing a specific metallocene compound and at least one synthetic resin selected from a propylene polymer different from the above propylene polymer, an olefin elastomer and an olefin polymer. 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 automobiles and electrical appliances, daily necessaries, various films and sheets.</p> |
