Paper Abstract

Increasing Use Of Isoimide Technology In Polyimide Processing Has Warranted Additional Application Of Analytical Techniques To Assay Concentration Of Polyisoimide Precursors Which Can Be Thermally Isomerized To Their Respective Polyimides Without Loss Of Volatiles. A Method Is Described Of Characterizing And Standardizing The Optimum Cure Temperature For A Given Polymer Blend By Plotting The Ratio Of The Characteristic Ir Bands For The Representative Of The Isoimide And Imide Configurations. Ftir Spectroscopy Is Used To Monitor The Extent Of Isomerization For A Number Of Polymer Blends And Mixtures Of Pbi (Polybenzimidazole) And A Polyisoimide Oligomer.
