PROCESS FOR PRODUCTION OF ETHYLENE-VINYL ALCOHOL COPOLYMER COMPOSITION, AND PROCESS FOR PRODUCTION OF ETHYLENE-VINYL ALCOHOL COPOLYMER PELLET |
摘要 |
<p>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.</p> |
