Epoxy resin Fourier-transform infrared spectroscopy

This article will review the impact of two powerful new techniques for characterizing epoxy resins at the molecular level — Fourier transform infrared spectroscopy (FT-IR) and high resolution nuclear magnetic resonance (NMR) of solids. Fortunately, these two techniques are not inhibited appreciably by the insoluble nature of the cured resin. Consequently, substantial structural information at the molecular level can be obtained. In this article, the basis of the methods will be briefly described in order to appreciate the nature of the methods followed by a description of the work on epoxies to date and finally some indication will be given of the anticipated contributions of these methods in the future. 

In addition to HPLC, elemental analysis, vapor phase osmometry. Fourier Transform Infrared Spectroscopy (FTIR), GC/MS, and NMR techniques were applied to verify the purity of the resin samples. Epoxy equivalent weights (EEW) were determined by the standard nonaqueous titration method (J ) using chloroform as the solvent. A correction for tertiary amine was obtained by conducting the titration in the absence of the quaternary halide. ...
