Abstract
A polypropylene resin composition comprising from 5 to 99.9 wt % of a polypropylene resin (A) and from 95 to 0.1 wt % of an ethylene/.alpha.-olefin copolymer elastomer (B) satisfying the following conditions (a) to (d): PA1 (a) the .alpha.-olefin has a carbon number of from 4 to 20, PA1 (b) the .alpha.-olefin content is larger than 65 wt % and at most 95 wt %, PA1 (c) the density at 23.degree. C. is less than 0.88 g/cm.sup.3, and PA1 (d) no peak of crystal fusion is observed by a DSC method.
