    摘要： To provide a resin composition comprising an ethylene-vinyl alcohol copolymer (A) having an ethylene content of from 15 to 65 mol % and a degree of saponification of 95 mol % or more, a phosphoric acid salt (B) which can form a hydrate, and a dispersing agent (C), wherein the dispersing agent (C) comprises at least one species selected from the group consisting of aliphatic acid salts, glycerol aliphatic acid esters and aliphatic acid amides, the resin composition comprises (A) and (B) in amounts of from 50 to 99 parts by weight and from 1 to 50 parts by weight, respectively, based on 100 parts by weight of (A) and (B) in total, and the resin composition comprises (C) in an amount of from 1 to 20 parts by weight based on 100 parts by weight of (B). This resin composition excels in gas barrier property and also in moisture resistance at high temperatures and high humidities. Therefore, it is suitable for food packaging containers to be retorted.

    摘要： This invention provides a method for producing a saponified ethylene-vinyl acetate copolymer in which visible imperfections (particularly fish eyes) of the saponified copolymer is inhibited. In this invention, a mixture solution is prepared by adding water to a methanol solution after saponifying an ethylene-vinyl acetate copolymer, and insoluble materials are removed from this mixture solution. Various types of filter or centrifugal separator are used to remove insoluble materials. It is preferable that the weight ratio of methanol to water is from 5:5 to 9:1, the concentration of the saponified copolymer is from 30 to 60 wt %, and the temperature is from 55 to 80° C. This method is particularly suitable for producing a saponified ethylene-vinyl acetate copolymer having an ethylene content of 20 to 70 mol % and a saponification degree of at least 95 mol %.

    摘要： A method for producing an aqueous ethylene-vinyl alcohol copolymer (EVOH) composition that ensures efficient removal of alcohol not worsening the environment in and around working areas, and which provides EVOH pellets of the aqueous composition, which can be produced stably and can be washed rapidly, the method involving introducing an EVOH solution that contains at least 50 parts by weight, relative to 100 parts by weight of EVOH therein, of an alcohol having a boiling point of not higher than 100° C., into a vessel, and contacting it with water vapor in the vessel, thereby letting the alcohol out along with water vapor and taking the resulting aqueous EVOH composition that contains from 0 to 10 parts by weight of the alcohol and from 10 to 500 parts by weight of water, relative to 100 parts by weight of EVOH therein, out of the vessel; and the EVOH pellets obtained by cutting the aqueous EVOH composition obtained in the method.
