摘要： 二过碘酸合铜(Ⅲ)络离子在小分子氧化反应动力学方面的研究已有报道[1～3]。但用于自由基聚合反应方面的研究至今尚未见报道。本文系用膨胀计法研究了Cu(Ⅲ)为氧化剂、丙烯酰胺(简称AM)为还原剂引发AM聚合反应动力学,得到聚合速率方程及聚合物分子量,探讨了反应机理。

Abstract: The kinetics of acrylamide polymerization initiated by potassium diperiodatocuprate (Ⅲ ) was studied in alkaline medium. The results indicate the equation of the polymerization rate is as follows: Rp=k[AM]1.8[Cu( Ⅲ )]0.76 and the molecular weight of a polymer decreases with increasing in Cu( Ⅲ). The effects of reaction conditions on polymerization rate were also studied.

Key words: Potassium diperiodatocuprate( Ⅲ ), Acrylamide, Redox initiation
