Abstract
Abstract This invention provides certain complex molecules which possess excellent solubility in water and excellent reactivity making them useful in the manufacture of non-woven products and processes for their preparation. The compositions are comprised of structural units derived from a higher polycarboxylic acid and about one mole of a di-epoxide per carboxyl group, about 0.5 to 1.5 moles of an alkoxy polyoxyalkylene compound and about 0.5 to 1.5 moles of an alkanolamine neutralized with a lower monocarboxylic acid.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
A binding agent comprising per molecule a center consisting of a polycarboxylic acid to each carboxyl group of which a diepoxide has been attached and the terminal epoxy groups of which bear an alkoxy polyoxyalkylene group and dialkanol ammonium group neutralized by carboxylate ions obtained by reacting a dimer, trimer or higher oligomer obtained by the polymerization of unsaturated C 16 -C 20 fatty acids with one mol (per carboxylic group) of a diglycidyl ether of a compound selected from the group consisting of Bisphenol A, Bisphenol F and polyoxypropylene glycol, further reacting with about 0.5 to 1.5 mols of an alkoxy polyoxyalkylene compound having terminal alkoxy and hydroxyl groups, a molecular weight from about 200 to 400 and alkylene groups containing 2 or 3 carbon atoms and 0.5 to 1.5 moles of an alkanol amine the alkanol groups of which contain 2 or 3 carbon atoms and finally neutralized to a pH of 4-9 with a monocarboxylic acid containing 1 to 4 carbon atoms.
Claim 2
Dependent Claim
