ABSTRACT OF THE DISCLOSURE Certain complex molecules and processes for their preparation provided herein. The molecules comprise structural units derived from higher polycarboxylic acid and one mole of a di-epoxide per carboxyl group, 0.5 to 1.5 moles of an alkoxy polyoxyalkylene compound, 0.5 to 1.5 moles of an alkanolamine containing nitrogen atoms which have been reacted with a lower monocarboxylic acid to a product having a pH value of 4-9, preferably from 6-8, and possess excellent solubility in water and excellent reactivity. The ideal structure of the molecules thus comprises, per molecule, a centre consisting of a polycarboxylic acid, to each carboxylic group of which a de-epoxide has been attached, of which part of the terminal epoxide groups bear alkoxy polyalkylene oxide groups and dialkanol ammonium groups which are neutralized by carboxylate ions derived from a lower carboxylic acid. These products are useful as binding agents, which are water soluble and which are particularly suitable for use in the manufacture of non-woven products, e.g., felt, paper and inter- linings.
