The precise knowledge of rate coefficients is of key importance for the understanding and the application of radical polymerization processes. Propagation rate coefficients, k_p, of n‐pentyl methacrylate (PnMA) radical polymerization are measured in bulk and partly in toluene solution over an extended temperature range via pulsed laser polymerization (PLP) in conjunction with size‐exclusion chromatography (PLP–SEC). Rate coefficients, k_t^i,i, for termination of two radicals of chain length i are determined as a function of chain length by single‐pulse PLP in conjunction with electron paramagnetic resonance spectroscopy (SP–PLP–EPR). The as‐obtained data that allow for modeling PnMA polymerization kinetics and product properties at moderate degrees of monomer conversion are compared with reported data for several other alkyl methacrylates. A distinct family behavior of this group of monomers is seen.

甲基丙烯酸正戊酯自由基聚合动力学的研究

速率系数的精确知识对于自由基聚合过程的理解和应用至关重要。传播速率系数，ķ _p，的ñ -戊基甲基丙烯酸酯（PNMA）自由基聚合是成批和部分在超过经由与大小排阻层析结合脉冲激光聚合（PLP）的温度范围内的甲苯溶液中测量（PLP-SEC） 。率系数，ķ_吨^我，我，为链长的两个基团的终止我通过单脉冲PLP结合电子顺磁共振波谱（SP-PLP-EPR）确定链长的函数。所获得的数据可以在中等单体转化率下模拟PnMA聚合动力学和产物性能，并与其他几种甲基丙烯酸烷基酯的报告数据进行了比较。可以看到这组单体的明显的家族行为。
