Patent ID: 6867252

Claim:
A propylene-based resin composition comprising: (A) 60 to 90% by weight of a propylene-based resin, (1) comprising 78 to 88% by weight of 23° C. p-xylene insolubles (a) and 12 to 22% by weight of 23° C. p-xylene solubles (b), (2) the insolubles (a) having an isotactic pentad fraction of 95% or higher, a relaxation time (τ) of 0.01 to 0.35 second at an angular frequency (ω) of 10°/sec when measured by melt viscoelastometry and a molecular weight distribution index (PDI) of 1 to 18 which is expressed by ω 2 /10ω 1 wherein ω 1 is an angular frequency at which a storage modulus (G′) as measured by melt viscoelastometry is 2×10 2 Pa and ω 2 is an angular frequency at which a storage modulus (G′) as measured by melt viscoelastometry is 2×10 4 Pa, and (3) the solubles (b) having an intrinsic viscosity [η] (in decalin at 135° C.) of 3.3 dl/g or higher and an ethylene unit content of 43% by weight or smaller; (B) 0 to 10% by weight of a rubber-like elastomer; and (C) 10 to 30% by weight of talc.
