- Copolymerization of acrylic acid and acrylamide with high concentration.
説明
In order to obtain anionic flocculant under an extremely high concentration of monomer, copolymerization of acrylamide and acrylic acid has been carried out. This provided a high rate of polymerization, where the polymerization could be accomplished within 10 minutes in batch scale. The products obtained were of ultra-high molecular weight, and were of high enough quality to be polymeric flocculants. To characterize the polymerization under high concentration, kinetic analysis was performed. The inter-molecular chain extension was found to be involved along with the normal polymerization process. The activation energies, 29.8kcal/mol, of polymerization and monomer reactivity were evaluated; these values were comparable with those reported in previous studies. A continuous reactor was tentatively constructed on the bench scale on the basis of the conditions obtained in the batch scale experiments. The reactor was made by modifying a steel belt conveyer; here uniform developing of the monomer solution onto the belt and deoxidization of monomer solution were essential. The continuous polymerization was successful: thus the polymerization could be done in the same manner on batch scale.
