摘要 |
Means for solving the problems The thermoplastic resin composition (X1) of the present invention comprises (A1), (B1), (C1), and optionally (D1) below:
1 to 90 wt% of an isotactic polypropylene (A1);
9 to 98 wt% of a propylene/ethylene/±-olefin copolymer (B1) containing 45 to 89 mol% of propylene-derived structural units, 10 to 25 mol% of ethylene-derived structural units, and optionally, 0 to 30 mol% of C 4 -C 20 ±-olefin-derived structural units (a1);
1 to 80 wt% of a styrene-based elastomer (C1); and
0 to 70 wt% of an ethylene/±-olefin copolymer (D1) whose density is in the range of 0.850 to 0.910 g/cm 3 , wherein (A1)+(B1)+(C1)+(D1) = 100 wt%. |
