A process for producing a cationic resin, thermosetting water soluble

摘要

Disclosed are novel wet strength resins for paper. The resins are produced by reacting an epihalohydrin, such as epichlorohydrin, with an aminopolyamide-polyureylene intermediate derived by reacting methylbisaminopropylamine with oxalic acid or a diester of oxalic acid and with urea.
