The traditional methods used for recovery of thermoset resins are summarized and their drawbacks are stated respectively in this review. The research including the popular synthesis and preparation methods of degradable epoxy resins is introduced in detail . The degradation characteristics and mechanism of three degradable epoxy resins are illustrated . Finally , the drawbacks of the mentioned degradable epoxy resins are presented . The prospects of development for degradable epoxy resins is analyzed . Key words 　epoxy resins ; curing ; degradation ; design and synthesis Contents 1 　引言 1 　Introduction
