Abstract:
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.
