Abstract: Provided is a method for preparing an epoxy compound having an alkoxysilyl group effectively by using a mild catalyst as well as an aromatic alcohol ring-opening agent. The preparation method for an epoxy compound having an alkoxysilyl group includes: performing a ring opening step by reacting an epoxy compound having an epoxide group, which is a starting material, with an aromatic alcohol ring-opening agent in the presence of a phosphine-based catalyst and an optional solvent so as to obtain an intermediate having a partially ring-opened epoxide group; and performing an alkoxysilylation step by reacting the intermediate having a partially ring-opened epoxide with isocyanate alkoxysilane.

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.
