Аннотация: A setup and a technique for optical measurements intended for evaluating the content of unbound compounds in an epoxy polymer are described. The principle of operation of the setup is based on measurements of the spectra of absorption of infrared (IR) radiation by condensed products of evaporation of unbound components. The needed mass of a sample is about 0.01 g. The results of measurements of the IR radiation absorption as a function of the concentrations of the mixture components-ED-22 epoxy resin, isomethyltetrahydrophthalic anhydride (hardener), and a cure promoter (N integral D-606/2)-are presented. The relative content of chemically unbound components in the structure of a polymer matrix is evaluated as a function of the hardener concentration, thus allowing determination of the stoichiometric ratio of the initial components of an epoxy mixture. The obtained results are compared to those obtained by the extraction method.
