摘要：
A process for the feedstock recycling of thermoset materials treats the material with a partially hydrogenated aromatic hydrocarbon at a temperature of from 200 to 350° C. in the presence of an amine. In the case of epoxy resin materials an amine is not needed if processing is carried out at temperatures of from 300 to 350° C.
