| titleOfInvention | Production of aqueous solutions of cationic thermosetting resins |
| abstract | ABSTRACT OF THE DISCLOSURE A durable aqueous solution of a thermosetting resin having a relatively high solid content which imparts a high degree of wet strength to paper, is pro-duced by the reaction of an aliphatic dicarboxylic acid with a polyalkylenepolyamine to form a polyamidopoly-amine, which is successively subjected to reaction with epichlorohyrin, the first reaction being carried out using a molar ration of aliphatic dicarboxylic acid to polyalkylenepolyamine of 1 : 1.0 to 1.2 and continued until the viscosity ar 25°C of 50% aqueous solution of resulting polyamidopolyamine reaches 400 to 1,000 cps, and the second reaction being carried out using epichloro-hydrin in an amount of 1.6 to 1.7 moles per mole of the polyamide secondary amine and continued until the viscosity at 25°C of 15% aqueous solution of the resulting product reaches 30 to 150 cps. |
