    摘要： The present invention provides a resin composition including an ethylene-vinyl alcohol copolymer (EVOH) and a polyamide resin and having outstanding properties in terms of long-term run stability, appearance, and hot water resistance in melt molding. In this resin composition, 70 mol % or more of all the terminal ends of the polyamide resin are blocked with units including an imide structure. At least a portion of the units containing an imide structure may be units containing a cyclic imide structure.

    摘要： The present invention is directed to a resin composition superior in barrier properties and also superior in flexibility, secondary processability and interlayer adhesiveness. The present invention is also directed to an environmentally friendly method for producing a resin composition, the method releasing no carboxylic acid such as acetic acid to the peripheral environment. The invention provides an EVOH resin composition (F) which has a content of an alkali metal salt (A), in terms of the alkali metal, of 0.1 to 20 µmol/g and a content of a carboxyl acid or its salt (C), in terms of carboxylate radical, of 2 µmol/g or less and which has an ethylene content of 5 to 60 mol% and a saponification degree of from 80 to 99 mol%. In addition, the invention provides a resin composition comprising the EVOH resin composition (F) and an EVOH having an ethylene content of 5 to 60 mol% and a degree of saponification of 99.2 to 100 mol%.

    摘要： The present invention provides a resin composition which comprises EVOH and a thermoplastic resin other than EVOH and which generates less odor and therefore is suitable for food packaging applications. The invention also provides an environmentally friendly method for producing a resin composition, without releasing any carboxylic acid such as acetic acid to the peripheral environment. A resin composition containing less carboxylate group is obtained by contacting an ethylene-vinyl alcohol copolymer resin with an aqueous solution containing both carbon dioxide gas and at least one additive selected from the group consisting of an alkali metal salt (A) and a boron compound (B) and then melt kneading with a thermoplastic resin (G) other than EVOH.
