| titleOfInvention | Method for producing polyacetal copolymer |
| abstract | A high quality polyacetal copolymer is economically provided through a simple process.nn n n The present invention includes a raw material supply step of supplying a raw material containing trioxane or the like to the reaction apparatus 1; the polymerization ambient temperature at which the conversion rate of the reaction apparatus (D/C described below) reaches 0.5 is maintained at 100 ° C or less, and thereafter Further carrying out a polymerization reaction to obtain a polymerization reaction step of the reaction mixture; a vaporization separation step of vaporizing and separating the unreacted monomer from the aforementioned reaction mixture at an ambient temperature of 115 ° C or higher and less than 140 ° C; The unreacted monomer resupply step supplied to the raw material supply step; and the polyacetal copolymer recovery step of recovering the polyacetal copolymer from the reaction mixture. Thereby, the polyacetal copolymer D is a total supply monomer C defined by the sum of both the monomer A newly supplied to the reaction apparatus 1 and the monomer B recovered from the reaction apparatus 1 and resupply. The weight ratio D/C is 0.7 or more, and D/A is 0.85 or more. |
