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。
In this paper, aqueous polymerization was used to study the polymerization reaction of acrylonitrile initiated in alkaline medium by the redox initiator system of potassium diperiodate (Ⅲ) potassium-urea. The effects of various factors on the polymerization rate, molecular weight and molecular weight distribution of the polymer were investigated. The polymerization mechanism was also discussed.
