Abstract
A method for degrading an acid anhydride epoxy cured product includes performing a mixing step and performing a degradation step. In the mixing step, an acid anhydride epoxy cured product is mixed with an alcohol amine compound so as to form a degradation system. In the degradation step, the degradation system is heated to a degradation temperature so that the acid anhydride epoxy cured product is degraded into a polyol.
Claims22
A method for degrading an acid anhydride epoxy cured product, comprising:
- performing a mixing step, wherein the acid anhydride epoxy cured product is mixed with an alcohol amine compound so as to form a degradation system, and the alcohol amine compound has a structure represented by formula (I):
- wherein R2 is each independently a methyl group or a hydrogen atom, p is an integer from 0 to 6;
- and
- performing a degradation step, wherein the degradation system is heated to a degradation temperature so that the acid anhydride epoxy cured product is degraded into a polyol.
7-9. (canceled)
14-15. (canceled)
A method for degrading an acid anhydride epoxy cured product, comprising:
- performing a mixing step, wherein the acid anhydride epoxy cured product is mixed with an alcohol amine compound so as to form a degradation system, and a weight ratio of the alcohol amine compound to the acid anhydride epoxy cured product is 5:1 to 20:1;
- wherein the acid anhydride epoxy cured product is synthesized from a linear epoxy compound and an acid anhydride compound;
- and
- performing a degradation step, wherein the degradation system is heated to a degradation temperature so that the acid anhydride epoxy cured product is degraded into a polyol.
