Zusammenfassung:	Provided is a method for producing an oxymethylene copolymer having high physical properties. The method for producing an oxymethylene copolymer includes a step of copolymerizing trioxane and a comonomer copolymerizable with the trioxane in the presence of a cationic polymerization catalyst and a polymerization control agent, wherein the polymerization control agent is a cyclic ether having a 4-membered or more ring and containing one oxygen atom. 本发明提供一种具有高物性的氧亚甲基共聚物的制造方法。该氧亚甲基共聚物的制造方法包括在阳离子性聚合催化剂和聚合控制剂的存在下将三噁烷和能够与上述三噁烷共聚的共聚单体共聚的工序，上述聚合控制剂为含有1个氧原子的4元环以上的环状醚。
