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 %. |
