Abstract
Novel carboxylic acid metal salt/amine complexes of the formula EQU (A.sup..crclbar.).sub.2 Me.sup.2+ .multidot.NH.sub.2 --R.sub.1 --NH.sub.2 in which A is the anion of cyanoacetic acid, pyrrolidonecarboxylic acid, maleimidylcarboxylic acid, succinylimidylcarboxylic acid, benzenesulphonic acid or toluenesulphonic acid or of a methanephosphonic acid monoester or benzenephosphonic acid monoester, Me.sup.2+ is a divalent metal cation and R.sub.1 is a long-chain polyoxyalkylene radical, are obtained by reacting 1 mol of a carboxylic acid metal salt of the formula EQU (A.sup..crclbar.).sub.2 Me.sup.2+ with 1 mol of a diamine of the formula EQU H.sub.2 N--R.sub.1 --NH.sub.2 in a polar organic solvent and in the temperature range of 25.degree. to 200.degree. C. to give the complex compounds of the formula. The novel complex compounds are valuable curing agents for epoxide resins and in mixtures with epoxide resins have an advantageous storage stability.
