(57) [Summary] [Structure] (1) Polypropylene resin, (2) Acrylic ester copolymer rubber, and (3) (i) 0.01 to 15% by weight of a carboxyl group or an acid anhydride group. 100 parts by weight of modified polyolefin, (ii) 1 to 500 parts by weight of acrylic acid ester copolymer elastomer containing 0.01 to 5% by weight of a carboxyl group, and (iii) An olefin-based thermoplastic elastomer resin composition comprising an elastomer-modified polyolefin in which the metal salt is 0.1 to 30 equivalents of the amount of the carboxyl group or acid anhydride group of (i). And (1), (2) and (3) are heated and mixed while the crosslinking of (2) is carried out, the method for producing the olefinic thermoplastic elastomer composition. [Effect] Excellent mechanical properties. |
