The effects of a tin maleate stabilizer and of typical processing lubricants (Wax E and calcium stearate) on the photo-oxidation of PVC have been examined. The latter are found to have a relatively minor effect but the tin maleate stabilizer introduces an induction period to photo-oxidation, related

A~lract--The reaction between cumene hydroperoxide (CHP) and anhydrous hydrogen chloride under various conditions of temperature and concentration has been studied in an inert solvent (chlorobenzene) and in an oxidisable medium (cumene). The kinetics were first order with respect to each reactant :
The effects of lubricants and a tin maleate stabilizer on the mechanochemical and thermal degradation of PVC during processing have been studied at 170' and 210. The protective mechanism of the two types of additive were found to be complementary in that the lubricants reduced the severity of the me
