Beschreibung
Zusammenfassung:	The present invention provides a polypropylene resin composition which contains a polypropylene resin (A) comprising a continuous phase that is composed of 55 to 73% by mass of a propylene polymer (a1) and a rubber phase that is composed of 27 to 45% by mass of a copolymer (a2) of ethylene and an α-olefin having 3 to 10 carbon atoms. La présente invention concerne une composition de résine de polypropylène qui contient une résine de polypropylène (A) comprenant une phase continue qui est composée de 55 à 73 % en masse d'un polymère de propylène (a1) et une phase caoutchouc qui est composée de 27 à 45 % en masse d'un copolymère (a2) d'éthylène et d'une α-oléfine contenant de 3 à 10 atomes de carbone. 本発明は、プロピレン重合体（ａ１）５５～７３質量％からなる連続相と、エチレンと炭素数３～１０のαオレフィンとの共重合体（ａ２）２７～４５質量％からなるゴム相とを含むポリプロピレン系樹脂（Ａ）を含有するポリプロピレン系樹脂組成物を提供する。
