HIGH SOLIDS GLYOXALATED POLYACRYLAMIDE

摘要

Disclosed is a glyoxalated polyacrylamide polymer composition comprising a glyoxalated polyacrylamide polymer in an amount of from about 10% to about 30% by weight of said composition, and comprising an aqueous medium, wherein said glyoxalated polyacrylamide polymer is obtained from the reaction between glyoxal and a cationic polyacrylamide base polymer comprising at least about 30% by weight cationic monomer, wherein the cationic polyacrylamide base polymer has a molecular weight ranging from about 3,000 Daltons to about 13,000 Daltons, and wherein the cationic polyacrylamide base polymer comprises from about 70% to about 50% by weight, acrylamide monomer and from about 30% to about 50%, by weight, cationic monomer copolymerizable with said acrylamide monomer. The polymer is used in paper making.
