The star-shaped poly(sodium acrylate),initiated by potassium diperiodatocuprate(Ⅲ)(DPC)/dipentaerythritol(DPE),was synthesized through redox radical polymerization of sodium acrylate(AA-Na) in alkaline medium.
以二羟基二过碘酸合铜(Ⅲ)钾(简称DPC)为氧化剂与季戊四醇二聚体(简称DPE)组成氧化还原体系,在碱性介质中引发丙烯酸钠(简称AA-Na)通过自由基聚合得到了星形聚丙烯酸钠(简称SSPAA-Na)。
