Synthesis mechanism and properties of epoxy resins modified with adipic acid

Abstract

The mechanism of diepoxide and adipic acid (AA) reaction in the presence of benzyltriethylammonium chloride and 1,4-diazobicyclo[2,2,2] octane has been proposed. The thermal stability of the oligoester obtained via chemical modification of the dioxydiphenylpropane diglycidyl ether with AA and epoxy-oligoesteric mixtures with its participation has been studied. The viscoelastic properties of films based on epoxy-oligoesteric mixtures containing Epidian-5 epoxy resin, TGM-3 oligo-esteracrylate, AA modified Epidian-5 and polyethyl-polyamine have been determined.
