The present invention is a composition excellent in transparency, flexibility, rubber elasticity, heat resistance, impact resistance, abrasion resistance, etc., a composition excellent in rigidity and impact resistance, excellent balance of whitening resistance, wear resistance, heat sealability, rubber properties, heat resistance, wear resistance, Provided is a polypropylene resin composition having excellent flexibility.n n n In the signal chart which set the peak which exists in the highest magnetic field among the signals derived from CH (methine) of the structural unit derived from C4-C20 alpha-olefin by 13 C-NMR to 34.4 ppm, about 22.0- A specific propylene-α that satisfies the following relations (i) and (ii) for an absorption strength A of 20.9 ppm and an absorption strength C of about 19.0 to 20.6 ppm, which are attributed to propylene methyl. It relates to a polypropylene resin composition containing an olefin copolymer and a molded article thereof.n n n (A / C) x 100? … (Ⅰ)n n n (B / C) x 100? 60? … (Ii) |
