采用毛细管气相色谱-质谱联用技术对两种聚偏二氯乙烯包装膜在空气中的热解产物进行了分析。检测到大量的氯代芳烃和多环芳烃。重要的产品是氯化苯、苯乙烯、苯酚、苯乙炔、萘、联苯和苯并呋喃。这些化合物大多是新发现的。还发现，即使在200/sup 0/C下热解也产生许多氯代芳香族化合物。在600/sup 0/C的热解物中检测到少量的氯二苯并呋喃和二氯二苯并呋喃。
Two kinds of wrapping film made of poly(vinylidene chloride) were pyrolyzed under an air stream, and the pyrolysis products were identified by capillary gas chromatography-mass spectrometry. Many chlorinated aromatic compounds and polynuclear aromatic hydrocarbons were detected. Important products were chlorinated benzenes, styrenes, phenols, phenylacetylenes, naphthalenes, biphenyls, and benzofurans. Most of these compounds were newly detected. It was also found that many chlorinated aromatic compounds were produced by pyrolysis even at 200/sup 0/C. Small amounts of chlorodibenzofuran and dichlorodibenzofuran were detected in the pyrolysate at 600/sup 0/C.
