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. |

1. 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,
wherein the total amount of the cationic monomer and anionic monomer is from 9 mol % to 50 mol %, and wherein the cross linking agent is a monomer having at least two unsaturated double bonds. |
