reactivities of methacrylate monomers toward the attack of a radical, the copolymerizations of a series of nuclear-substituted phenyl methacrylates with styrene were investigated. From the results, the monomer reactivity ratios and the Alfrey-Price Q, and e values were determined. It was found that the relative reactivities toward the polystyryl radical were not correlated with the ordinary Hammett equation
为了阐明烷基取代基对甲基丙烯酸酯单体对自由基攻击的反应性的影响,研究了一系列核取代的甲基丙烯酸苯酯与苯乙烯的共聚反应。根据结果,确定了单体反应性比率和 Alfrey-Price Q 和 e 值。发现对聚苯乙烯基团的相对反应性与普通的哈米特方程无关,但通过包含取代基共振贡献项的修正哈米特方程获得了线性关系。因此,认为取代的甲基丙烯酸苯酯的反应性取决于由取代基引起的极性和共振效应。
