Patent ID: 8592674

Claim:
A thermoplastic resin composition (X1) comprising (A1), (B1), (C1), and optionally (D1) below: 1 to 90 wt % of an isotactic polypropylene (A1); 9 to 98 wt % of a propylene/ethylene/α-olefin copolymer (B1) containing 45 to 89 mol % of propylene-derived structural units, 10 to 25 mol % of ethylene-derived structural units, and 1 to 30 mol % of C 4 -C 20 α-olefin-derived structural units (a1); 1 to 80 wt % of a styrene-based elastomer (C1); and 0 to 70 wt % of an ethylene/α-olefin copolymer (D1) whose density is in the range of 0.850 to 0.910 g/cm 3 , wherein, the total of (A1), (B1), (C1), and (D1) is 100 wt %, and a melting point of propylene/ethylene/α-olefin copolymer (B1) is not observed when measured with a differential scanning calorimeter (DSC).
