发明名称 Resin composition comprising ethylene-vinyl alcohol copolymer with good interlayer adhesiveness
摘要 <p>Disclosed are a resin composition comprising an ethylene-vinyl alcohol copolymer and a multi-layered structure comprising the resin composition. The resin composition comprises an ethylene-vinyl alcohol copolymer which contains from 500 to 2000 ppm, in terms of the metal, of an alkali metal salt (A) and from 0.05 to 4.5 mu mol /g of a carboxylic acid (B), where the ratio of the content ( mu mol/g) of a carboxylic acid (b1) having a molecular weight of at least 75 and its salt to the total content ( mu mol/g) of the carboxylic acid (B) and its salt is at least 0.1; or comprises an ethylene-vinyl alcohol copolymer which contains from 500 to 2000 ppm, in terms of the metal, of an alkali metal salt (A), from 10 to 500 ppm of a carboxylic acid (b2) having a molecular weight of smaller than 75, and from 10 to 500 ppm, in terms of the phosphate radical, of a phosphate compound (C). The resin composition has extremely good adhesiveness, and its moldings have good appearance with few gels and fish eyes. When molded, the resin composition ensures good long-run workability and recyclability, and the recycled resin composition is yellowed little.</p>
