Polypropylene-based resins and polypropylene-based resin compositions

摘要: Disclosed are a polypropylene-based resin and composition having well-balanced, high-level flowability, stiffness impact resistance. The has an MI of from 30 to 70 g/10 min 25° C. xylene-soluble content, x, 5 15% by weight, in which the component is such that (a) its ethylene unit z, 20 30% (b) intrinsic viscosity, [72], indecalin at 135° not smaller than 2.00 dl/g, xylene-insoluble (c) y (% weight), satisfies following: 100y/[y×(1-x/100)+x]≦1.13z-16.6, (d) GPC, content constituent molecular weight 10 6 2% (e) 40 130 min, (f) stereospecificity index 98.5%. comprises (A) 45 90% resin, (B) 50% ethylenic copolymer, (C) 0 25% talc.
