The carboxyl group of the free acids was found to be of primaary importance in increaing the rate of oxidation and enhancing chain scission. Oleic and linoleic acids exhibited synergistic pro-oxidant activity as a result of their co-oxidation. Chain breaking antioxidants such as butylated hydroxytoluene (BHT) helped protect polyisoprene from fatty acid promoted autoxidation ER -
