摘要
以水为溶剂 ,APS -SHS氧化还原引发体系 ,研究了丙烯酸及其共聚物的合成。结果发现 ,SHS既是还原剂 ,又是链转移剂 ,其用量 >3%时可得到分子量 <2万 。
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.
