<p>A propylene resin composition comprising: (A) 60 to 90 wt. % propylene resin which (1) comprises 78 to 88 wt. % 23 °C p-xylene-insoluble component (a) and 12 to 22 wt. % 23 °C p-xylene-soluble component (b) and in which (2) the component (a) has an isotactic pentad content of 95 % or higher, a relaxation time τ as determined under specific conditions of 0.01 to 0.35 seconds, and a molecular weight distribution index (PDI) as determined under specific conditions of 1 to 18 and (3) the component (b) has an intrinsic viscosity [θ] of 3.3 dl/g or higher and an ethylene unit content of 43 wt. % or lower; (B) 0 to 10 wt. % rubbery elastomer; and (C) 10 to 30 wt. % talc. The resin composition is injection-molded to give an interior automotive member.</p> |
