Polyamide-epichlorohydrin wet strength resins that are

A process for making an acid stabilized, base reactivatable resin. A polyalkylene polyamine is reacted with a C3-8 sat. aliphatic dicarboxylic acid to form a water soluble polyamide. The polyamide is reacted with epichlorohydrin to form an aq. soln. of cationic thermosetting resin that contains reactive cross-linking groups and chlorohydrin groups. This soln. is reacted with sufficient water-sol. acid to convert some of the reactive cross linking groups to aminochlorhydrin acid anion groups and to stabilize any groups containing epichlorophydrin at the chlorohydrin stage. These resins have improved stability against gelation without the necessity of readjusting pH following a ageing period. If the acid stabilization reduces wet-strength, this can be regained by addition of sufficient base to neutralize the acid used for stabilization. For incorporation in aqueous paper pulp suspensions for preparing wet-strength paper.
