| Abstract: | The reaction conditions of synthetic powdered cationic polyacrylamide (CPAM) through Non homogeneous Mannich reaction of non ionic polyacrylamide (NPAM) were studied. The relations of swelling capacity and aminating degree of NPAM in the water alcohol medium with swelling time. Volume ratio of water to alcohol and molecular weight of NPAM are discussed.The effects of reaction time on aminating degree,solubility and swelling behavior of CPAM are also studied. The results show that non homogeneous Mannich reaction of NPAM can be accomplished in the water alcohol medium. The effect of molecular weight of NPAM on aminating reaction is little.The structure of CPAM was identified by IR spectrum. |
