Effect of light stabiliser tinuvin 1130 and tinuvin 292 on the pholodegradalion of butadiene/chlorobutyl/rrithiol rubber systems.

Abstract

The photocrosslinking and photodegradation of butadiene/clobutyl rubber system have been studied by IR spectra analysis. In the presence of the photostabilisers, the photocrosslinking of butadiene/clobutyl rubber system was decreased. The influence of the contents of the UV-absorber Tinuvin 1130, radical scavenger Tinuvin 292 and their combinations on the light deterioration of the rubber system have been evaluated
