Chlorinated pyrolysis products of co-pyrolysis of poly(vinyl chloride) and poly(ethylene terephthalate)

The influence of poly(vinyl chloride) on poly(ethylene terephthalate) pyrolysis was investigated. Products of degradation of this two-polymer mixture were separated by gas chromatography and chloroorganic components were identified. Chloroesters of terephthalic and benzoic acids were found. Mass spectra and fragmentation pattern for identified compounds have been shown. The signals from two fragments at m/z 211 and 213 were proposed to be used for a fast identification of such compounds. (C) 2002 Elsevier Science B.V. All rights reserved.
