| Zusammenfassung: | A propylene polymer composition comprising a propylene polymer and an ethylene-α-olefin copolymer (provided that the ethylene-α-olefin copolymer is not the propylene polymer), the propylene polymer composition satisfying requirement (I):Requirement (I) an absolute value of a difference between a die swell ratio at a shear rate of 24 sec−1 and a die swell ratio at a shear rate of 6,080 sec−1 is 0.29 or less.One embodiment of the present invention is a propylene polymer composition which additionally satisfies the requirement (II).Requirement (II): The ethylene triad chains (EEE) in an ortho-dichlorobenzene-insoluble fraction are 2.0 mol % or more. |
