✦ Synopsis

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 mechano-chemical process whereas the tin maleate stabilizer reduced the rate of hydrogen chloride elimination during the second stage by reacting with allylic chlorine, with conjugated unsaturation and with hydrogen chloride.

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

Unstabilized PVC processed at 170 and 210 C was found to undergo immediate mechanochemically induced thermal oxidation with the formation of unsaturation and peroxides. The peroxides were partially in the form of cross-links between polymer molecules at this stage and were manifested in the form of
