Abstract: The present invention relates to relates to an amine composition, the use of said amine composition, a curing agent composition, a curable composition, a cured epoxy resin as well as methods for producing said amine composition, said curing agent composition, said curable composition and said cured epoxy resin. Furthermore, the present invention relates to reactive polyamide resins obtainable from said amine composition, a method for their manufacture and their use. Method for the production of the amine composition comprises following steps: A) conversion of formaldehyde (FA), hydrogen cyanide (HCN) and ethylenediamine (EDA); B) hydrogenation of the reaction mixture obtained in step A); and C) purification of the hydrogenated reaction mixture obtained in step B), wherein the purification step C) comprises 1) removal of hydrogen; 2) removal of organic solvent and water; 3) passing the reaction mixture obtained in step 2) to an evaporator operated at a pressure in the range of 5 to 500 mbar and a temperature in the range of 100 to 250 °C; 4) removal of the gaseous phase from the evaporator; and 5) condensation of the gaseous phase.
