Title
(EN) POLYACETAL COPOLYMER AND METHOD FOR PRODUCING SAME
(ZH) 聚缩醛共聚物和其制造方法
Abstract
(EN)
The objective of the present invention is to provide: a novel polyacetal copolymer having excellent productivity and mechanical properties by introducing a group having a new structure; and a method for producing the same. The objective of the present invention has been achieved by means of a polyacetal copolymer obtained by copolymerizing at least a trioxane and a siloxane compound (A) represented by formula (1). In formula(1), R1 represents a monovalent aliphatic hydrocarbon group having 1-6 carbon atoms or an aromatic hydrocarbon group having 6-10 carbon atoms, and X represents an organic group having R1 or an epoxy group. However, at least two of a plurality of Xs are organic groups having an epoxy group, and a plurality of R1s and a plurality of Xs may respectively be the same or different from each other.
