基于ESR技术测定的自由基浓度和终止速率常数,用严格的非稳态动力学公式第一次获得了AIBME引发MMA本体聚合体系各个转化率下的引发效率f数据,提出了扩散控制引发反应模型。在反应全程中理论结果与实验结果相符。
Based on the determination of the free radical concentration and the termination rate constant by ESR technique, the data of initiation efficiency at various conversion rates of AIBME-initiated bulk polymerization system were obtained for the first time using a rigorous unsteady kinetic equation. The diffusion-controlled reaction model . The theoretical results are consistent with the experimental results throughout the reaction.
