利用红外光谱法测定反应转化率研究原子转移自由基聚合反应动力学。在环己酮溶液中,以卤代烃为引发剂,过渡金属卤化物与配位剂2,2’-联吡啶为催化体系,进行了苯乙烯聚合。分别就反应温度、反应物浓度和引发体系对苯乙烯聚合速率的影响进行了动力学测定,证实了原子转移自由基聚合具有活性聚合的特征,同时计算并讨论了苯乙烯原子转移自由基聚合反应的动力学数据。
Study on Reaction Conversion Rate by Infrared Spectroscopy and Study on Kinetics of Atom Transfer Radical Polymerization. In cyclohexanone solution, halogenated hydrocarbon as initiator, transition metal halide and complexing agent 2,2’-bipyridyl as catalytic system, styrene polymerization was carried out. The effects of reaction temperature, concentration of reactants and the polymerization system on the polymerization rate of styrene were studied. The kinetics of the polymerization of styrene was confirmed. Atom transfer radical polymerization was confirmed to have the characteristics of living polymerization. At the same time, the effects of styrene atom transfer radical polymerization Kinetic data.
