CA 1188835

Abstract of the Disclosure Disclosed are novel water-soluble, thermosettable resinous compositions derived by reacting a precondensate of dicyandiamide, formaldehyde, a salt of a water-soluble poly- aminopolyamide and an ammonium salt with epihalohydrin, con- densing the reaction product with additional formaldehyde and then post-modifying the condensate with additional epihalo- hydrin or a nitrogen-containing compound. The resinous compo- sitions are cationic and have particular utility in the manu- facture of paper sized with cellulose reactive sizing agents such as ketene dimer sizing agents.
