Abstract
The effect of an organophosphoric insecticide on the thermooxidative degradation of the diglycidil ether-bisphenol A epoxy resin was investigated, using infrared spectroscopy, thermogravimetric and thermodifferential analysis, pyrolysis-gas chromatography and elemental analysis. The results indicated that studied organophosphoric insecticide exercises an influence upon the degradative process of uncured resin by catalysing its decomposition in the lower temperature region. At the same time, the tested insecticide promotes the formation of a phosphorus containing thermostable solid residue. Keyword: epoxy resin, organophosphoric additive, thermooxidative degradation
