摘　　要：以FT-IR为定量工具,分别测定了以环己烷、甲苯、氯仿、正丁醇、吡啶为溶剂20℃时甲基丙烯酸三丁基锡酯(TBTM)与甲基丙烯酸甲酯(MMA)辐射共聚的共聚参数。观察到表征TBTM活性的参数In1/r_2与溶剂的偶极矩成一线性关系;溶剂的极性对TBTM与MMA共聚的反应活性有影响。溶剂极性增加,TBTM反应活性下降。In this paper, the radical copolymerization of TBTM with MMAinitiated by radiation in various solvents were studied and the reactivity ratios werealso calculated. It is found that there is nearly linear relationship betweendipoletnoment of solvents and copolymerization activity of TBTM. The charging in thestructuer of TBTM in different solvents, which bring steric hindrance to thecopolymerization, was presented to explain tbese results.
