Abstract:

A series of polymers has been analyzed using TG-MS techniques. Detection and identification of volatile gases evolved under programmed heating rates are correlated with sample weight loss to provide information concerning polymer stability. For the case of a series of perfluoro- and perfluoroether- substituted bibenzoxazole elastomers, a mechanism of thermal degradation is proposed.
