Claim:
A propylene resin composition comprising: (A2) 5 to 80 wt % of a syndiotactic propylene polymer satisfying the requirement (a) below; (B) 5 to 80 wt % of a soft propylene copolymer satisfying the requirement (b) below and having a melting point of less than 100Â° C. or not showing a melting point in differential scanning calorimetry (DSC); (C) 0 to 40 wt % of one or more elastomers selected from ethylene elastomers (C1) and styrene elastomers (C2); and (D) 15 to 80 wt % of an inorganic filler (wherein the total of (A2), (B), (C) and (D) is 100 wt %): (a) the melting point according to differential scanning calorimetry is not less than 100Â° C.; (b) MFR measured at 230Â° C. under 2.16 kg load in accordance with ASTM D 1238 is in the range of 0.01 to 100 g/10 min, and at least one of the requirements (b-1) and (b-2) is satisfied: (b-1) the syndiotactic triad fraction (rr fraction) as measured by 13 C-NMR is not less than 60%; and (b-2) the copolymer contains 55 to 90 mol% of structural units derived from propylene and 10 to 45 mol % of structural units derived from at least one olefin selected from C2-20 Î±-olefins (excluding propylene) (with the proviso that the total of the structural units derived from propylene and the structural units derived from the C2-20 Î±-olefin(s) (excluding propylene) is 100 mol %), and an intrinsic viscosity [Î·] (dL/g) as measured in decalin at 135Â° C. and the MFR (g/10 min, 230Â° C., 2.16 kg load) satisfy the following relationship: 1.50Ã—MFR (âˆ’0.20) â‰¦[Î·]â‰¦2.65Ã—MFR (âˆ’0.20) .
