反相离子对抑制色谱法分析聚酰亚胺树脂溶液单体成分

Analysis of Polyimide Resin by Reversed Phase Ion Pair Suppression Chromatography

使用Ｃ１８反相液相色谱柱，以乙腈和水作为流动相，以甲基磺酸作为离子对试剂，并加入高氯酸钠以增强离子强度，采用等度洗脱，建立了单体反应物原位聚合型（ＰＭＲ型）的聚酰亚胺树脂溶液中单体成分分析的反相离子对抑制液相色谱法。并对树脂单体材料的纯度以及ＰＭＲ型树脂溶液中的单体及单体异构体成分进行了分析。

This paper describes the analysis of insitu polymerization of monomeric reactants (PMR) polyimide resin solution by reversed phase ion pair suppression chromatography. the mobile phase consists of acetonitrile and water. The methyl sulphonic acid was used as an ion-pair reagent in the mobile phase. The addition of sodium perchlorate was required to increase the ionic strength of the mobile phase. The information was obtained on monomeric isomer distribution of PMR polyimide resin solution and purity of prepared materials.
