Thermogravimetric-Mass Spectrometric Polymer Analysis

Abstract

Thermogravimetric-mass spectral (TGMS) analyses of the volatile products of thermal degradation of sixteen polymers are reported. Perfluoro- and perfluoroether-substituted benzoxazoles comprise the majority of the samples. Perfluoro-substituted benzoxazoles, in general, display one temperature region of volatile-product formation. The volatile products tend to be perfluorocarbons. Perfluoroether-substituted benzoxazoles, depending upon the structure and location of the substitution, tend to display one or two temperature regions of volatile-product formation. The temperature at which the high-temperature process occurs coincides with that for decomposition of the perfluoro-substituted benzoxazoles. Some of the other samples analyzed include acetylene-terminated imides and quinoxolines. No appearance of volatile products from the imides or quinoxolines was noted at or below the curing temperature.
