Water soluble polyalkanolamides and a process to prepare same by reacting polycarboxylic acid or its anhydride, ester of halide derivative with at least one alkanolamine and optionally with a polyamine and removing the condensation by product water, alcohol or hydrogen halide. These compounds are useful as tackifying resins for creping adhesives.

Cette invention se rapporte à des polyalcanolamides solubles dans l'eau et à un procédé de préparation de ces polyalcanolamides qui consiste à faire réagir de l'acide polycarboxylique ou son dérivé anhydride, ester ou halogénure avec au moins une alcanolamine et éventuellement avec une polyamine, et à extraire l'eau sous-produit de condensation, l'alcool ou l'halogénure d'hydrogène. Ces composés sont utiles en tant que résines collantes pour des adhésifs de crêpage.
