Degradation of poly vinyl chloride during processing

10 Degradation of poly(vinyl chloride) during processing [Pg.170]

Processing of poly(vinyl chloride) causes both thermal oxidative and mechano-chemical degradation. [Pg.170]

With short processing times and particularly at lower temperatures, mechanochemical chain scission causes the formation of two end-chain [Pg.170]

In the presence of air (oxygen) polymer peroxy (PO2) radicals are formed [Pg.172]

Chlorine radicals (Cl ) abstract hydrogen from a processed polymer and produce HCl [Pg.172]
