| titleOfInvention | Cationic thermosetting resin composition for improving wet strength of paper |
| abstract | WHERE R is alkylene or arylene with (b) an amino carbonyl compound, (c) a diamine or polyalkylene polyamine, and (d) itaconic acid, and (2) one or both of two secondary polyamine polyamide polymers B and C, the former being prepared by reacting reactants (b) and (c), above, and (e) epichlorohydrin, and the latter secondary polymer C being prepared by reacting reactants (a), (b), (c) and (e), above. The mixture of polymers is rendered thermosetting by further reaction with additional epichlorohydrin. A considerable number of resins for imparting wet strength to paper have been developed in recent years. Most of these resins are of the thermosetting type, thermosetting properties generally having been provided by means of crosslinking agents such as halohydrins. Cationic thermosetting resin compositions useful in imparting wet and dry strength to paper are formed of a mixture of (1) a primary water-soluble polyamine polyamide polymer A, prepared by reacting (a) a heterocyclic dicarboxylic acid of the formula: |
