摘要： An ethylene-vinyl alcohol copolymer alcohol solution comprising an ethylene-vinyl alcohol copolymer and an alcohol having a carbon number of not greater than 4 is brought into contact with an aqueous solution of at least one additive selected from a carboxylic compound, a boron compound and a phosphoric compound to replace a part or all of the alcohol with water, whereby an ethylene-vinyl alcohol copolymer composition containing the additive is prepared. This preparation process makes it possible to efficiently replace the alcohol in the ethylene-vinyl alcohol copolymer alcohol solution with water, and homogeneously incorporate the thermal stabilizer in the composition.

摘要： The invention provides a process for producing a saponified vinyl acetate polymer (a saponified ethylene-vinyl acetate copolymer in particular) which features a minimum of coloration of molding pellets, a well-inhibited emanation of an odor in melt-molding, a high transparency of the product film and a low incidence of fish-eyes in the film, and a process for producing a vinyl acetate polymer (particularly an ethylene-vinyl acetate copolymer) for use as the starting material for said saponified vinyl acetate polymer having said favorable properties. In accordance with the invention, either vinyl acetate alone or vinyl acetate and one or more other monomers are polymerized in the presence of a hydroxylactone compound and a polymerization catalyst. The resulting vinyl acetate polymer (particularly the ethylene-vinyl acetate copolymer) is then saponified.
