VAPOR PHASE INFRARED SPECTRA OF EPOXY RESIN COMPONENTS

摘要

The accuracy and resolving capabilities of the Perkin-Elmer-521 used to obtain the spectra presented in this report" are based on the carbon dioxide band at 667. cm-1 and associated bands as reported in the literature.nQuantitative measurements of the methylene chloride bands seem to have a reasonable degree of accuracy. However, quantitative measurements of ECPE and MPDA are very uncertain. The uncertainty results from the difficulty (1) of injecting, a-measured quantity of these compounds into the 20-meter gas cell and insuring that all have vaporized, and (2) of obtaining equilibrium conditions between solid/liquid and vapor.
