| Abstract: | The low-middle molecular weight polyacrylate sodium has been synthesized with air-sodium bisulfite as initiation system at low temperature by free radical solution polymerization. It was studied through orthogonal experiments that reaction conditions effected the molecular weight of polyacrylate sodium and the conversion ratio of monomer. The experiment results showed that the molecular weight of polyacrylate sodium was 5000~20000 under the different reaction conditions. |
