Abstract
Aromatic polyarene-phosphochloridates were prepared by condensation of various bis-phenols (4,4'-isopropylidenediphenol,4,4'-dihydroxydiphenyl sulphone, and 4,4'-dihydroxybi-phenyl) with phosphorus oxychloride in pyridine medium. These polymers were characterized by IR spectrophotometry. The isothermal decomposition of these polymers and their 2% mixtures with PVC were studied.
