【摘要】 苯乙烯在乙醇／水混合溶液介质中，在偶氮二异丁腈引发作用下，以聚乙烯基吡咯烷酮为稳定剂进行分散聚合反应，采用溴加成双键分析方法研究了苯乙烯分散聚合反应过程中单体转化率的变化，并讨论了引发剂浓度和反应温度对单体转化率的影响。更多还原

【Abstract】 The conversion percentage of monomer（styrene）during the dispersion polymerization of styrene,using α,α’-azobisisobutylonitrile as an initiator and Poly-N-vinylpyrrolidone as a steric stabilizer,in mix-medium was studied by double-bond analysis.The relationships between conversion percentage of monomer and concentration of initiator and reaction temperature were discussed.更多还原
