通过对种子乳液聚合的分子量分布的分析，确定了甲基丙烯酸正丁酯(BMA)自由基聚合中链转移为单体的平均动力学系数Hktr，Mi。在40℃和708℃之间的测量结果表明，数据符合Arrhenius指数型关系
The average kinetic coefficient for chain transfer to monomer hktr,Mi in the free-radical polymerization of n-butyl methacrylate (BMA) has been determined by the analysis of molecular weight distributions obtained by seeded emulsion polymerization under conditions such that chain transfer to monomer is the dominant chain-stopping event. Measurements between 40 and 708C gave data fitting an Arrhenius-type relationship with exponential
