ABSTRACT Novel, 1,2-Epoxy Resin products using unique poly- cyclic, aromatic, polycarboxylic acid products as cross- linking agents display satisfactory electrical properties and good Barcol hardness values. The process for prepar- ing these novel resin products involves admixing: a 1,2-epoxy resin containing on the average more than one 1,2-epoxy groups per molecule and the acid product derived from the nitric acid oxidation of naturally occurring solid carbonaceous material along with a suitable accelerator. The mixture is then subjected to a precure step which involves heating at temperatures between 50° and 150°C for from about five minutes to about six hours. The mixture is thereafter subjected to suitable molding conditions.
