    摘要: The present invention provides a resin composition based on crystalline polypropylene which includes: (a) 3-65% by weight of a component soluble in paraxylene of 23° C., (b) 35-97% by weight of a component soluble in paraxylene of 135° C. and insoluble in paraxylene of 23° C., and (c) 0-30% by weight of a compoent insoluble in paraxylene of 135° C. The component (a) soluble in paraxylene of 23° C. is composed substantially of an elastomeric constituent (a1) having a content of styrene or its derivative in the range of 0-35% by weight and an intrinsic viscosity (n) in the range of 0.1-5 dl/g, the component (b) soluble is paraxylene of 135° C. and insoluble in paraxylene of 23° C. is composed substantially of a crystalline polyproylene constituent (b1) having an isotactic pentad proportion (mmmm) of 97% or higher, a molecular weight distribution (Mw/Mn) of 6 or higher and a molecular weight distribution (Mz/Mw) of 6 or higher and the component (c) insoluble in paraxylene of 135° C. is composed substantially of a filler (c1).
