<p>There is provided a resin composition affording a melt-molded article having excellent gas barrier properties and flex crack resistance. The present invention relates to a resin composition comprising a polyvinyl alcohol polymer (A) having a 1,2-diol structural unit represented by the following general formula (1), a styrene-based thermoplastic elastomer (B), and a polyamide graft block copolymer (C) containing a polymer block of an aromatic vinyl compound and a polymer block of an olefinic compound in a main chain and having a graft chain composed of a polyamide:
wherein each of R 1 , R 2 , and R 3 independently represents a hydrogen atom or an organic group, X represents a single bond or a linking chain, and each of R 4 , R 5 , and R 6 independently represents a hydrogen atom or an organic group.</p> |
