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.

摘要： The present invention provides a process for producing pellet of EVOH comprising the steps of introducing an EVOH solution containing alcohol into an apparatus, contacting the solution with water in the apparatus to let out the alcohol with water and then letting out an EVOH hydrous composition from the above-mentioned apparatus (step 1); cutting the EVOH hydrous composition let out therefrom to obtain EVOH hydrous composition pellets (step 2); introducing the obtained EVOH hydrous composition pellets into a dryer to reduce a water content thereof (step 3); melt-kneading the pellets, whose water content is reduced, in an extruder (step 4); and cutting EVOH discharged from the extruder to obtain the pellet of EVOH (step 5). Thus, the EVOH hydrous composition obtained by removing alcohol without deteriorating the environment can be efficiently dried, and pellets having less thermal degradation in drying and a uniform shape can be obtained.
