Process for preparing ethylene-vinyl alcohol copolymer composition, and process for producing ethylene-vinyl alcohol copolymer pellets |
| abstract |
An ethylene-vinyl alcohol copolymer (EVOH) composition preparation process is provided, which comprises the steps of: feeding an EVOH alcohol solution into a tower type apparatus, the EVOH alcohol solution comprising 100 parts by weight of an EVOH and not less than 300 parts by weight of an alcohol having a carbon number of not greater than 4; bringing the EVOH alcohol solution into contact with water, and feeding out a part of the alcohol together with water from the apparatus to provide an EVOH water/alcohol mixture solution comprising 100 parts by weight of the EVOH, 10 to 200 parts by weight of the alcohol and 50 to 200 parts by weight of water; bringing the EVOH water/alcohol mixture solution into contact with water in an agitator container with stirring, and feeding out a part or all of the alcohol together with water from the container to provide an EVOH composition comprising 100 parts by weight of the EVOH, less than 10 parts by weight of the alcohol and 20 to 100 parts by weight of water. This preparation process makes it possible to efficiently replace the alcohol in the EVOH alcohol solution with water to provide a lower water content EVOH composition. |
