| titleOfInvention | Production method for polyacetal copolymer |
| abstract | Provided is a production method for a polyacetal copolymer that makes deactivation of a catalyst simple and efficient and that achieves a high polymerization yield and high quality using equipment that does not require a cleaning step and a process that involves a simple operation technique. The production method for a polyacetal copolymer uses trioxane as a main monomer (a) and a cyclic ether and/or a cyclic formal having at least one carbon-carbon bond as a comonomer (b). In the production method, a predetermined heteropoly acid is used as a polymerization catalyst (c) to perform copolymerization, a predetermined salt (d) is added to the reaction product, melt kneading processing is performed, and the polymerization catalyst (c) is deactivated. It is preferable that the heteropoly acid be selected from among phosphomolybdic acid, phosphotungstic acid, and the like. It is preferable that the salt (d) be selected from among sodium carbonate, sodium bicarbonate, sodium formate, and the like. |
