二过碘酸含铜(Ⅲ)钾—尿素氧化还原引发丙烯腈聚合反应的研究

Studies on the Redox Initiated Polymerization Acvlonitrile by Ier-veient Copper Cu(Ⅲ) and Urwa

本文采用水相沉淀聚合法研究了二过碘酸合铜(Ⅲ)钾—尿素组成氧化还原引发体系在碱性介质中引发丙烯睛聚合反应。测得了各种因素对聚合反应速率、聚合物分子量及分子量分布的影响,探讨了聚合反应机理。

Acrylonitrile(AN) redox polymerization initated with patassium diperidotocuprate(III )-ured binary systems was studied in alkaline medium. Eftecte of reaction conditions on polymerization rate and polymer molecular weight and molecular weight Distribution were studied.Initiated mechamism of polymerization was proposed.
