Notes:
In this work we have studied the stabilizing effect of several commercially available antioxidants on the free-radical photooxidation of butadiene rubber. Two kinds of stabilizers were investigated; hindered phenols: 2,4-di-t-butyl-p-hydroxytoluene, octadecyl-3-(3,5-di-t-butyl-4-hydroxyphenyl)-propionate and 2,4-bis(octylthio)-6-(4-hydroxy-3,5-di-t-butylanilino)-1,3,5-triazine; and amine stabilizers: N-isopropyl-N′-phenyl-p-phenylenediamine and N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine. Their stabilizing effect is mostly produced by scavenging the peroxy radicals formed during the initial steps of the photodegradation process. We also tested tri(nonylphenyl)phosphite associated with the phenoltriazine stabilizer. Of the additives studied in this work, octadecyl-3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate was the most effective photostabilizer for butadiene rubber.
