ABSTRACT:
The present invention relates to a propylene polymer composition comprising:
65 to 95% by weight of a propylene homopolymer having (a) an intrinsic viscosity ([.eta..sub.1 ]) of 0.5 to 3.5 dl/g, (b) a xylene soluble content at ordinary temperature (Xs) of not more than 3% by weight, and a difference (.DELTA[eta..sub.1 ]) between ([.eta..sub.1 ]) of xylene insoluble portion at the ordinary temperature and ([.eta..sub.1 ]) of xylene soluble portion at the ordinary temperature of not more than 0.5 dl/g, (c) an isotactic pentad fraction (IP) falling within the range represented by the following equation:
