Abstract: Byproducts of the oxidation of cycloalkanes, which react with primary and secondary amines, are condensed with polyvalent aliphatic amines. The condensation products are inexpensive and are suitable as epoxide resin hardners. The condensation products generally contain in chemically bound form about 50 percent or more of said byproducts. Resins hardened with the hardeners of the present invention surprisingly show increased impact strength.
