Abstract

In this work a non isothermal method was used based on Differential Scanning Calorimetry (DSC). The samples under study underwent the thermal treatment to different sweeping speeds and in oxygen presence to favor the water heater- oxidation of the material. Starting from the beginning temperatures of the oxidation (Ti) to different heating (b = 1, 3, 5, 7, 10, 15, 20 .C / min) and based on the adjustment of a model of prediction type Arrhenius antioxidant capacity of different preservatives was determined in  the resin  polymeric. The results indicate that I lower  the studied formulations the antioxidant capacity of the preservatives it is predicted, presented a good reproducibilidad of the results of Ti for DSC and demonstrating a good accuracy in this value according to the pattern of prediction type Arrhenius.
