The latter decomposes with chain scission and generation of a free radical which can continue the degradation . This autoxidation mechanism, particularly visible during the second stage of degradation attributed to the degradation of SS, is slowed by the presence of Irganox 1076 and resveratrol, which capture the free radicals formed. In addition, the MDI segment of the TPU which is a part of the hard segment (HS) can also be affected by thermooxidative degradation. According to the literature, it can be converted to benzophenone following reactions involving free radicals . The presence of resveratrol or Irganox 1076 reduces this phenomenon by scavenging the free radicals. Then, different gains in degradation temperatures can be obtained for the formulations with antioxidant compared to the neat matrix. . OIT of the neat matrix is 3 min, which is in line with literature values for this type of polymer . An improvement in OIT up to 6 min was obtained with the addition of 0.3 % of Irganox 1076. Moreover, no significant exotherm was observed for the formulation containing 0.3 % of resveratrol. These results also demonstrate excellent antioxidant activity of these molecules in a TPU matrix, with the thermo-oxidative stability provided by resveratrol far superior to the values obtained in the literature for stabilized TPUs .
