Combined pyrolysis and radiochemical gas chromatography for studying the thermal degradation of polymers

摘要

Pyrolysis gas chromatography and radioactive tracer techniques havebeen used independently to study the thermal degradation of polymers. Inthese laboratories the two techniques have been combined to elucidatesome of the mechanisms of the thermal degradation of epoxy resins andpolyimides. This paper describes the apparatus developed for this work.
