    摘要: The invention relates to resin systems useful for imparting dry-strength to paper without substantially increasing the paper's wet-strength wherein the resin system comprises a cationic component and an anionic component. The invention also relates to the process for incorporating these resin systems into paper and the paper produced containing the resin systems.

    摘要: Disclosed are novel wet strength resins for paper, said resins being derived by reacting an epihalohydrin, such as epichlorohydrin, with a polyamino-copolyamide derived by reacting methylbisaminopropylamine with (a) a diester of oxalic acid and (b) a diester of a saturated dicarboxylic acid containing at least 4 carbon atoms, the mole ratio of (a) to (b) being from about 0.25:1 to about 10:1.

    摘要: Disclosed are novel organic pigments adapted particularly for use as tillers for paper. The organic pigments are finely divided particles obtained by graft copolymerizing an ethylenically unsaturated monomer, such as styrene, onto a water-soluble cationic prepolymer in an aqueous solution and in the presence of a free-radical polymerization initiator.

    摘要: The present invention contemplates a process for forming polyaminoamide polymers formed by the reaction of a dibasic acid/ester with excess amounts of an amine; the intermediate polymer resulting therefrom; a process for synthesizing effective, high solids resins resulting from the reaction of intermediate polymers with an epihalohydrin; and the resultant high, solids resin. These resins may be used as wet strength resins in the papermaking industry.
