Continuous treatment method for saponified ethylene-vinyl acetate copolymer |
| abstract |
PROBLEM TO BE SOLVED: To provide an efficient treatment method for stably and continuously obtaining EVOH having little variation in characteristics (fluidity, heat discoloration resistance, etc.) and excellent in melt moldability. To do. SOLUTION: When treating a saponified ethylene-vinyl acetate copolymer (A) with an acid (B) and / or a salt thereof (C), the acid (B) and / or a salt thereof is preliminarily introduced from the top of a column reactor. A saponified ethylene-vinyl acetate copolymer (A ′) containing the salt (C) was charged, and an aqueous solution of the acid (B) and / or a salt thereof (C) was charged from the lower part of the reactor. A ′) and (B) and / or (C) , An excess aqueous solution of acid (B) and / or its salt (C) is taken out from the top of the reactor, and saponified ethylene-vinyl acetate copolymer treated from the bottom of the reactor. Are continuously taken out. |
