| Abstract: | The effect of 2,2′-thiodiethylbis-3-(3,5-di-tert-butyl-4-hydroxy-phenyl) propionate] (Irganox 1035) on the 9-methylanthracene sensitized photo-oxidation of styrene-butadiene copolymer (SBR) has been examined. It was found that the photo-oxidation of SBR is considerably inhibited by the Irganox. Irganox was found to be able to quench singlet oxygen as well as to scavenge alkoxyl radicals. |
