Abstract
A technique for the study of low temperature (up to 400C) thermal degradation of polymeric materials in both inert and reactive atmospheres is described. The technique utilizes a thermal desorb unit (CDS 320-011 Concentrator) coupled to a capillary gas chromatograph with mass spectrometric detection. Four styrene cross-linked thermoset resins, one vinyl ester (Derakane 510A) and three polyester (Hetron 99P, Hetron 197AT, and Vibrin F1029) resins were studied using this technique. The results indicate that the major degradation products of these resins at 300C and 400C result from the degradation of styrene cross-links and that the nature of the degradation products of the four resins are largely independent of the atmosphere in which the degradation takes place.
