Propylene-based polymer composition of the present invention, (A) 8 to 60.0 mol% of 41-95 weight part of propylene polymers whose Tm measured by DSC is 120 degreeC or more and 170 degrees C or less, and (B) propylene. In an amount of 1 to 30.0 mol% of the structural unit derived from ethylene, and in an amount of 1.0 to 10.0 mol% of the structural unit derived from an α-olefin having 4 to 20 carbon atoms. Also, 59 to 5 parts by weight of a propylene / ethylene / α-olefin copolymer having a B value of 0.9 or more and 1.5 or less, provided that the total of (A) and (B) is 100 parts by weight. have.n n n This polymer composition has excellent transparency, low temperature impact resistance, mechanical properties (such as flexibility or rigidity), and excellent heat resistance. |
