Preparation of Cationic Polyacrylamide Nanocomposite by Aqueous Two-Phase Polymerization Method

Abstract:

In order to improve the aqueous solutions viscosity and flocculation performance of cationic polyacrylamide, organic montmorillonite was added into polymerization system of polyacrylamide, the cationic polyacrylamide/dimethyl diallyl ammonium chloride/organic montmorillonite (CPAM/DMDAAC/MMT) nanocomposite was prepared by aqueous two-phase polymerization method. The influence of organic montmorillonite content, cationic monomer content, polyethylene glycol concentration, monomer concentration on the intrinsic viscosity of the CPAM/DMDAAC/MMT nanocomposite were discussed. The reaction conditions were optimized by orthogonal test. The chemical component and organic montmorillonite shape of the cationic CPAM/DMDAAC/MMT nanocomposite were analyzed by FTIR and XRD respectively. The results show that CPAM/DMDAAC/MMT nanocomposite with high aqueous solutions viscosity and beyond compare flocculation performance has been obtained by aqueous two-phase polymerization method. The CPAM/DMDAAC/MMT nanocomposite has been used very well as a flocculating agent.
