Process for producing oxymethylene copolyer |
| abstract |
A process for producing an oxymethylene copolymer by copolymerizing trioxane with at least one cyclic comonomer selected from the group consisting of cyclic ethers and cyclic formals, said process comprising (1) polymerizing trioxane alone or with a cyclic comonomer in the presence of a polymerization catalyst until the conversion of trioxane reaches 10 to 95%, and (2) thereafter adding a cyclic comonomer and a polymerization catalyst to the reaction system and continuing the polymerization. |
