<P>PROBLEM TO BE SOLVED: To provide a resin composition that is melt-molded into articles that have excellent gas-barrier properties and resistance to bending fatigue. <P>SOLUTION: This resin composition includes: a polyvinyl alcohol polymer (A) that contains a 1,2-diol structural unit represented by general formula (1); a styrene thermoplastic elastomer (B); and a polyamide graft block copolymer (C) that has a graft chain comprising a polyamide and the main chain of which contains an aromatic-vinyl-compound polymer block and an olefin-compound polymer block. In the formula, each of R<SP POS="POST">1</SP>, R<SP POS="POST">2</SP>and R<SP POS="POST">3</SP>independently represents a hydrogen atom or an organic group; X represents a single bond or a bond chain; and each of R<SP POS="POST">4</SP>, R<SP POS="POST">5</SP>and R<SP POS="POST">6</SP>independently represents a hydrogen atom or an organic group. <P>COPYRIGHT: (C)2012,JPO&INPIT |
