Does anyone know what's produced when PVC degrades? Is it hydrochloric acid? Is it PVC's reaction with oxygen that causes the degradation?
Thanks,

Chemical Name: Polyvinyl Chloride
Composition and Information on IngredientsChemical Name
Polyvinyl Chloride 99+%
Bis(2-ethylhexyl) Phthalate <1%
Vinyl Chloride Monomer <8.5ppm
Incompatibilities: Avoid contact with Strong oxidizers. Also, avoid contact with acetal or acetal copolymers and with amine containing materials during processing. At processing conditions, these materials are mutually destructive and involve rapid degradation.
Instable Conditions: Excessive temperatures (see Incompatibilities).
Decomposition Temperature: Prolong heating of product above 200°C or short term heating above 250°C. may result in rapid evolution of hydrogen chloride.
Decomposition products: Hydrogen Chloride, carbon monoxide, carbon dioxide and small amounts of benzene and aromatic and aliphatic hydrocarbons.
