Title:
METHOD FOR DEGRADING ANHYDRIDE EPOXY CURED PRODUCT, POLYOL PREPARED THEREFROM, AND THERMOSETTING RESIN
Document Type and Number:
WIPO Patent Application WO/2024/060177
Kind Code:
A1
Abstract:
The present invention provides a method for degrading an anhydride epoxy cured product, a polyol prepared therefrom, and a thermosetting resin. The method for degrading the anhydride epoxy cured product comprises carrying out a mixing step and carrying out a degradation step. In the mixing step, the anhydride epoxy cured product and an alcohol amine compound are mixed to form a degradation system, and the alcohol amine compound has a structure represented by formula (I), wherein various symbols in formula (I) are as defined in the description. In the degradation step, a degradation system is heated to a degradation temperature, such that the anhydride epoxy cured product is degraded to form the polyol. Therefore, the alcohol amine compound is heated to decompose the anhydride epoxy cured product, and the product polyol obtained therefrom can be applied to preparation of unsaturated polyester resin, such that the purpose of recycling is achieved.
