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。
FT-IR was used as a quantitative tool to measure the radiation copolymerization of TBTM and MMA at 20 ℃ with cyclohexane, toluene, chloroform, n-butanol and pyridine as solvent Of the copolymerization parameters. It has been observed that the parameter In1 / r2 characterizing the activity of TBTM has a linear relationship with the dipole moment of the solvent; the polarity of the solvent has an influence on the reactivity of the TBTM copolymerization with MMA. Solvent polarity increased, TBTM reactivity decreased.
