Carboxy-containing peroxy oligomer (CPO) has been synthesized via the reaction of peroxy derivative of ED-24 epoxy resin with free peroxy and epoxy groups with adipic acid in the presence of benzyl triethylammonium chloride. The effect of catalyst amount, reaction temperature and process time on the reaction rate has been determined. The effective rate constants and activation energies have been calculated. CPO synthesis procedure has been developed. CPO structure has been confirmed by chemical and IR-spectroscopic analyses. CPO was studied as an additive for the cross-linking of epoxy-oligoesteric mixtures based on ED-20 epoxy resin and TGM-3 oligoesteracrylate. Using IR-spectroscopy the chemism of the mentioned cross-linking has been determined.
