The Effect of Thermal Processing History on the Photooxidation of Polymers

Abstract: The processing of several polymers involves an initial mech anochemical stage resulting in damage to the polymer chai and sensitization to subsequent photooxidation. In the cas of PVC, unsaturation and peroxides are produced during the first minute of processing and a tin stabilizer that acts by retarding the formation of peroxides and unsaturation is an effective photostabilizer. Polyolefins are stabilized against UV light by the removal of peroxides produced during processing. The latter are effective photos… Show more
