Title
(EN) POLYACETAL COPOLYMER AND PRODUCTION METHOD THEREOF
(JA) ポリアセタール共重合体およびその製造方法
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a novel polyacetal copolymer excellent in productivity and mechanical characteristics by introducing a group having a new structure and to provide a production method of the polyacetal copolymer.

SOLUTION: There is provided a polyacetal copolymer produced by copolymerizing at least a trioxane and (A) a siloxane compound represented by formula (1). (In formula (1), R1's each represent a 1-6C monovalent aliphatic hydrocarbon group or a 6-10C aromatic hydrocarbon group and X's each represent an organic group having R1 or an epoxy group, provided that two or more of a plurality of X's are organic groups having an epoxy group and a plurality of R1's and a plurality of X's, respectively, may be the same as or different from each other.)

【課題】本発明の目的は、新たな構造を有する基を導入することにより、生産性、機械的特性に優れた新規なポリアセタール共重合体およびその製造方法を提供することにある。
【解決手段】本発明の目的は、少なくともトリオキサンおよび(A)式(1)で表されるシロキサン化合物とを共重合させたポリアセタール共重合体、によって達成された。

(式(1)中、Rは炭素数1〜6の一価脂肪族炭化水素基または炭素数6〜10の芳香族炭化水素基、Xは、Rまたはエポキシ基を有する有機基をそれぞれ表す。ただし複数存在するXのうち2以上はエポキシ基を有する有機基であり、複数存在するR、Xはそれぞれ同一であっても異なっても構わない。)
