<P>PROBLEM TO BE SOLVED: To obtain a resin composition comprising an ethylene-vinyl alcohol copolymer, which has excellent appearances with less coloring, few fish eyes (gels or hard spots) and streaks, is excellent in long-run workability when melt-molded, is recovered in a less-colored state, is excellent in low odor property and exerts excellent interlayer adhesiveness when fabricated into laminates; and to provide a multilayer structure. <P>SOLUTION: The resin composition comprising an ethylene-vinyl alcohol copolymer is characterized in that: when heated in a nitrogen atmosphere at 220°C, MFR (at 230°C under a load of 10.9 kg) of the composition shows a minimum value after the start of heating; the MFR shows a maximum value (MFRmax) after showing the minimum value; carboxylic acid (A) of 0.05-4 μm/g is contained; and the composition contains 0.005-1 pt.wt. lubricant based on 100 pts.wt. of ethylene-vinyl alcohol copolymer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
