✦ Synopsis

It is shown that antioxidants previously reported to be u.v. stabilizers can be distinguished by their mode of action into two categories. These are melt stabilizers, which destroy hydroperoxides during the processing operation, and u.v. stabilizers, which have the additional ability to destroy hydroperoxides during u.v. exposure. The interdependence of the chemical changes occurring during processing and on u.v. exposure are demonstrated.

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
