Stabilisers against dehydrochlorination

Whilst such stabilisers have found use in many chlorine-containing polymers their main application has been with polyfvinyl chloride). These additives will be considered in Chapter 12.

Polyvinyl Chloride. It is well-known how various attempts have been made to stabilise PVC against dehydrochlorination by salts, usually of divalent metal ions - as long chain alkylcarboxylates of Cd(II), Ba(U), Zn(II) [96]. Biswas and Moitra [102] recently established that the 3d metal ions incorporated in PVC-DMG-complex enhance the thermal stability of PVC in the order.
