On October 23, 2014, Qin, Bing; Li, Xin; Liang, Bo published a patent.Electric Literature of 5455-98-1 The title of the patent was Novel cyclic acetal, cyclic ketal diamines epoxy curing agents and degradable polymers and composites based thereon. And the patent contained the following:
The title curing agent can generate a degradable crosslinked polymer by performing polymerization reaction with an epoxy resin. The degradable crosslinked polymer can be degraded in a mixed system of acid and solvent under the condition of heating and stirring. This reinforced composite is prepared using the curing agent, the epoxy resin, and auxiliary materials. This reinforced composite can be degraded in a mixed system of acid and solvent under the condition of heating and stirring, and can be recovered and reutilized after neutralization. This reinforced composite has high mech. performance, and wide range of application. The experimental process involved the reaction of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione(cas: 5455-98-1).Electric Literature of 5455-98-1
