WET STRENGTH POLYAMINOPOLYAMIDE RESINS FOR PAPER

摘要

Disclosed are novel wet strength resins for paper. The resins are produced by reacting an epihalohydrin, such as epichlorohydrin, with a polyaminopolyamide derived by reacting methylbisaminopropylamine with oxalic acid, a diester of oxalic acid, or mixtures containing oxalic acid or a diester of oxalic acid and one or more different saturated dicarboxylic acids or their esters.
