Document Type and Number:
Japanese Patent JP6938180
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a polyacetal copolymer that makes it possible to obtain a polyacetal copolymer having high thermal stability while operating or using stably a polymerization reaction device.SOLUTION: The present invention provides a method for producing a polyacetal copolymer by polymerization of trioxane with cyclic ether and/or cyclic formal under the presence of a polymerization catalyst, where the polymerization catalyst is a metal halide having a metal element of from the third period to the sixth period and from the third group to the 16 group in the periodic table.SELECTED DRAWING: None
