| titleOfInvention | Method for producing ethylene-vinyl alcohol-based porous membrane |
| abstract | PROBLEM TO BE SOLVED: To provide a production method capable of easily obtaining an ethylene-vinyl alcohol-based porous membrane having extremely excellent water permeability as compared with a conventional ethylene-vinyl alcohol-based copolymer membrane. To do. A temperature T1 containing an ethylene-vinyl alcohol-based copolymer and a solvent defined by the formula (1) as main components. Is cooled to T2 at an average cooling rate of 200 ° C./sec or less after film formation, or formed into a film while cooling to T2 at an average cooling rate of 200 ° C./sec or less, and then the solvent is removed. It is achieved by doing. a / b ≧ 10 and b ≦ 1% by weight (1) (where a is the solubility of the ethylene-vinyl alcohol copolymer in the solvent at the temperature T1, and b is the temperature T 2 is the solubility of the ethylene-vinyl alcohol copolymer in the solvent. However, 30 ° C ≦ T1 ≦ 250 ° C, −10 ° C ≦ T2 ≦ 60 ° C, T2 + 10 ≦ T1 |
