Title:
アルコキシシリル基を有するエポキシ化合物の製造方法、アルコキシシリル基を有するエポキシ化合物、それを含む組成物、及びその用途
Document Type and Number:
Japanese Patent JP6852039
Kind Code:
B2
Abstract:
Provided are a preparation method of an epoxy compound having an alkoxysilyl group in which an increase in the epoxy equivalent weight (EEW) of the epoxy compound is minimized because alkoxysilylation occurs through a simple one-step reaction using a hydroxyl group formed during the synthesis of the epoxy compound, an epoxy compound having an alkoxysilyl group prepared by the method, a composition comprising the same, and a use thereof. The method includes the reaction of an epoxy compound having a hydroxyl group with an isocyanate alkoxysilane in the presence of amine-based base catalyst, wherein the epoxy compound having an alkoxysilyl group has a mole ratio of [epoxide group]:[alkoxysilyl group] of n:1 ranging from 2:1 to 10:1, and an EEW increase of the epoxy compound having an alkoxysilyl group is less than 260/n. The epoxy compound has good physical properties when being cured.
