ABSTRACT:
The propylene polymer composition of the invention comprises, as its essential components, a specific propylene polymer [A] described below and a propylene block copolymer [B]. In addition to the propylene polymer [A] and the propylene block copolymer [A], the propylene polymer composition may contain a thermoplastic elastomer [C] selected from polystyrene.polyethylene/poybutylene.polystyrene block copolymers and ethylene/.alpha.-olefin random copolymers, or may further contain an inorganic filler [D]. The propylene polymer [A] used in the invention has the following characteristic properties:
(1) a boiling heptane-insoluble component is contained in said polymer in an amount of not less than 96% by weight,
