本文用液相色谱和凝胶色谱对双酚A、双酚S型低聚芳砜及α,ω-双甲基丙烯酸聚芳砜酯大分子单体进行了组分分析,通过改合成条件、测定数均分子量等辅助手段确定液相色谱各峰的归属,计算其分子量及分子量分布指数,并对两种方法测定的结果进行了比较。用液相色谱观察低聚体每个组分的含量及其反应过程中的消长情况比凝胶色谱清晰。
In this paper, the components of bisphenol A, bisphenol S oligomeric aryl sulfone and α, ω-bismethacrylate polyaryl sulfone macromonomer were analyzed by liquid chromatography and gel chromatography. Determination of number average molecular weight and other auxiliary methods to determine the ownership of the liquid chromatography peak, calculate the molecular weight and molecular weight distribution index, and the results of the two methods were compared. The content of each component of the oligomer as observed by liquid chromatography and the growth and decline over the course of the reaction were clearly clearer than the gel chromatography.
