Studies on thermal decomposition are presented for various isomers of poly (phenylene phthalamide) (PPPA). The major thermal decomposition products identified are benzene, aniline, benzonitrile, and phenylenediamine isomers. Production of larger amount of amines was found for the meta-rich PPPA. This is explained in terms of a tentative non-radical process including an overlapping of benzene rings. The process for amine-production from PPPA in the thermal decomposition accounts for the decomposition at the lower temperatures of meta-rich PPPA recognized by the thermogravimetry.
