| titleOfInvention | Method for producing polyacetal copolymer |
| abstract | It provides high quality polyacetal copolymer economically in a simple process. The present invention relates to a raw material feed step of feeding a raw material containing trioxane or the like to a reactor (1) and a raw material feed step of feeding a raw material containing trioxane or the like to a reactor (1) A step of carrying out a further polymerization to obtain a reaction mixture, a step of vaporizing and separating the unreacted monomer from the reaction mixture at a temperature of 115 ° C. or more and less than 140 ° C., And a polyacetal copolymer recovery step of recovering the polyacetal copolymer from the reaction mixture. Thereby, the polyacetal copolymer (A) for the entire supply monomer (C) defined by the sum of the monomer (A) newly supplied to the reaction apparatus (1) and the monomer (B) recovered and re- (D / C) of 0.7 or more, and D / A is 0.85 or more. |
