Low Temperature Thermal Degradation Studies of Styrene Cross-Linked Vinyl Ester and Polyester Resins
Abstract
A technique for the study of low temperature (up to 400C) thermal degradation of polymeric materials in both insert 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 Virbrin 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 products of the four resins are largely independent of the atmosphere in which the degradation takes place. At lower temperatures, i.e., 100C and 200C, the compounds detected appear to result from the volatilization of uncured reactants.
