Products obtained by mixing an aminopolycarboxylic or polyaminopolycarboxylic acid with an amidazole or an imidazoline, usable as hardeners and latent accelerators for epoxy resins

摘要

Organic chemistry. The invention relates to products obtained by mixing an imidazole of formula I or an imidazoline of formula II with a polycarboxylic acid of formula III or IV. <IMAGE> where R1-R6 = H or a hydrocarbon radical, n = 0-6 and m = 2-6 A1 = -CH2COOH A2-A5 = H, an alkyl radical, -CH2COOH, -CH2CH2OH, -CH2CONHR, -CH2CHOHCH3, -CH2-CH2-SO3 or -CH2COOR where R = alkyl, and X = divalent hydrocarbon radical. Use as hardeners and/or accelerators for epoxy resins.
