| Abstract: | Syntheses of ploy(sodium acrylate)and its copolymers with water as solvent and APS-SHS as redox initiator are studied.The results show that SHS is not only reducing agent,but also chain-transfer agent.Colorless or pale yellow transparent polymer that the molecular weight is less than 20000 is obtained when the amount of SHS is larger than three of pereent of the amount of monomer. |

| Keywords: | Low molecular weight PAANa Coploymer Sodium sulfite Chain-Transfer agent |
