| titleOfInvention | Process for producing acetal polymer and copolymer |
| abstract | (57) [Summary] [Structure] In the polymerization or copolymerization of trioxane, at least one of a phenol, a phenol-substituted compound and a sterically hindered phenol is used as a polymerization catalyst in an amount of 1 per total amount of monomers. It is a manufacturing method of an acetal polymer or a copolymer in which an amount of 100 PPM is mixed. [Effect] It is possible to obtain a high polymerization yield and prevent the formation of tar-like precipitates generated in the catalyst solution. |
