Abstract:
1. A method for preparing a thermoplastic resin composition comprising melt-mixing (A) a thermoplastic elastomer composition comprising (i) an ethylene-vinyl alcohol copolymer and (ii) an acid anhydride-modified or epoxy-modified rubber dispersed in said ethylene-vinyl alcohol copolymer (i), and (iii) 0.1 to 5 parts by weight of a first crosslinking agent with respect to 100 parts by weight of modified rubber (ii) which constitutes thermoplastic elastomer composition (A), with (B-2) a thermoplastic elastomer composition comprising (i) at least one resin selected from unmodified polyamide resins and modified polyamide resins, and (ii) an acid anhydride-modified or epoxy-modified rubber dispersed in said at least one resin (i), and (iii) 0.1 to 2 parts by weight of a second crosslinking agent with respect to 100 parts by weight of modified rubber (ii) which constitutes thermoplastic elastomer composition (B-2).
