DIALDEHYDE MODIFIED ACRYLAMIDE TYPE POLYMER AND METHOD FOR PREPARING SAME

摘要

The invention provides a dialdehyde modified acrylamide type polymer for paper making, which is obtained by reacting a dialdehyde with an acrylamide type base polymer, wherein the acrylamide type base polymer is formed by copolymerization of an acrylamide type monomer, a cationic monomer and/or an anionic monomer and a cross linking agent. The invention further provides a method for preparing said dialdehyde modified acrylamide type polymer. The dialdehyde modified acrylamide type polymer according to the invention has improved stability while maintains excellent enhanced performance.
