Resumen

It is a well known fact that rubbers need the addition of antioxidants to avoid deterioration during the different stages (storage, processing and end use); therefore, the importance of knowing the oxidation and stabilization reactions of these materials is obvious. Thermodynamic considerations are followed by a description of an experimental program in which interactions between antioxidant and rubber were studied by using DSC. It is shown that it is possible to evaluate the efficiency of antioxidants in rubber, using the increase in T//i of the rubber on adding antioxidant in a known concentration. The creosote bush resin chloroform extract is more efficient in synthetic than natural rubbers. The increase in E//a can be explained by the formation of peroxy-quinolinic intermediates in the slow stage of the reaction and it is possible to calculate the E//a based on this same increase, when the relationships between the reaction and T//i, and between E//a/N calculated by Gorbachev and T//i, are known.
