ABSTRACT:
The polysalt which consists essentially of a specified acrylamide-styrene-acrylic acid interpolymer and a water-soluble cationic polyamine having a molecular weight in excess of 1,000 (the molar ratio of the anionic to the cationic substituents in the anionic polymer and in the polyamine being within specified ranges) is an efficient strengthening agent for paper. Compositions of the polysalts and an ionization suppressor for the anionic components therein can be employed as beater additives in paper manufacture at a mildly acid pH leading to a nearly neutral paper having excellent dry strength and, if desired, wet strength.
