Abstract Copolymers of styrene (STY) and methylmetacrylate (MMA) are widely employed due to the low price of the starting monomers coupled with their synthetic versatility. A chromatographic method was developed for the simultaneous determination of the conversion degree of the single components of the polymer during the copolymerization reaction and the composition of the produced copolymer. The crude reaction mixture is directly analyzed during the reaction with only a dilution pretreatment. Accordingly, the method allows quick and simple monitoring of the reaction as it proceeds.

测定聚（苯乙烯-r-甲基丙烯酸甲酯）聚合过程中单体转化率和组成的 HPLC 方法

摘要 苯乙烯 (STY) 和甲基丙烯酸甲酯 (MMA) 的共聚物由于起始单体价格低廉以及合成的多功能性而被广泛使用。开发了一种色谱方法，用于同时测定共聚反应过程中聚合物单一组分的转化率和生成的共聚物的组成。在反应过程中直接分析粗反应混合物，仅进行稀释预处理。因此，该方法允许在反应进行时快速且简单地监测反应。
