Abstract

An aqueous solution of a cationic thermosetting resin having a pH of 3.4 to 3.6 is obtained by reacting equimolar proportions of diethylene triamine and adipic acid to form (a) a water-soluble polyamide which is then reacted in aqueous solution with (b) epichlorohydrin and (c) ammonium hydroxide in a molar ratio (a): (b): (c) of 1: 0.5: 2.5. In the example the course of reaction is controlled by measuring the rate of viscosity increase which is reduced by lowering the temperature or increased by adding NaOH. When the Gardner-Holdt viscosity is between BBC and BC formic acid is added and the mixture rapidly cooled. It the pH is not as specified it is adjusted with formic acid. The solution may be used to impart wet-strength to paper.ALSO:An aqueous solution of a cationic thermosetting resin having a pH of 3.4 to 3.6 and obtained by reacting in aqueous solution in the molar ratio 1:0.5:2.5 (a) a water-soluble polyamide prepared from equimolar amounts of diethylene triamine and adipic acid, (b) epichlorohydrin and (c) ammonium hydroxide (see Division C3) is used under acid or alkaline conditions in the production of wet-strengthened paper.
