ABSTRACT:
Disclosed are a polypropylene-based resin and a polypropylene-based resin composition having well-balanced, high-level flowability, stiffness and impact resistance. The polypropylene-based resin has an MI of from 30 to 70 g/10 min and a 25.degree. C. xylene-soluble content, x, of from 5 to 15% by weight, in which the 25.degree. C. xylene-soluble component is such that (a) its ethylene unit content, z, is from 20 to 30% by weight, and (b) its intrinsic viscosity, [72], indecalin at 135.degree. C. is not smaller than 2.00 dl/g, and in which the 25.degree. C. xylene-insoluble component is such that (c) its ethylene unit content, y (% by weight), satisfies the following:
