| titleOfInvention | Method for producing polyacetal resin |
| abstract | (57) [Abstract] [Problem] Excellent surface appearance even in the case of a thin molded product, Provided is a method for producing a polyacetal resin having both impact resistance. SOLUTION: Trioxane and a cyclic ether and / or cyclic formal are used in producing a polyacetal resin by carrying out bulk polymerization using a trioxane, a cyclic ether and / or a cyclic formal, and a molecular weight modifier as raw materials using a cationic polymerization catalyst. Or a mixture of trioxane and a cyclic ether and / or cyclic formal and a part of a molecular weight regulator, and then supplying the cationic polymerization catalyst, and then adding the whole or a part of the remainder of the molecular weight regulator to the reaction product. Is supplied in one or more stages. |
