| titleOfInvention | Method for processing ethylene-vinyl alcohol copolymer solution |
| abstract | Provided is a method for processing an ethylene-vinyl alcohol copolymer solution, which comprises continuously substituting a part of the solvent in the solution with water to produce a high-concentration ethylene vinyl alcohol copolymer solution without gelling. For this, an ethylene-vinyl alcohol copolymer solution is fed into a column vessel selected from a plate column and a packed column, and a part of the solvent in the solution is substituted with water in the column vessel. Preferably, a solvent-water mixed vapor is fed into a plate column or a packed column through its lower part, and an ethylene-vinyl alcohol copolymer solution is fed thereinto through a part higher than the part through which the mixed vapor is fed into the column, whereby the copolymer solution is kept in contact with the mixed vapor in countercurrent flow so that a part of the solvent in the copolymer solution is substituted with water. |
