The possibility of epoxy resin carboxy-containing derivative (CDER) obtaining has been studied on the basis of dianic epoxy resin ED-24 and adipic acid (AA). The synthesized CDER contains epoxy and carboxy groups at the same time. Used catalysts were benzyltriethylammonium chloride (BTEACh); 1,4-diazobicyclo[2,2,2]octane; N,N-dimethylaminopyridine; 18-Crown-6, potassium hydroxide, triethylamine and 18-Crown-6+ZnCl2 catalytic system. The effect of the catalyst nature and amount, reagents ratio, process temperature and time on the reaction proceeding between ED-24 and AA has been determined. The structure of CDER synthesized in the presence of BTEACh and its characterics were confirmed by IR-spectroscopy. Using industrial dianic epoxy resin ED-20 the cross-linking of polymeric composites containing 10, 20 and 30 mass parts of CDER has been investigated at 413 K in the presence of polyethylenepolyamine.
