TL;DR: The kinetic approach on thermal stabilization of LDPE in the presence of 7 chalcone compounds is presented in this paper. But the results show that the depletion of antioxidant is a first order process.
Abstract: The kinetic approach on thermal stabilization of LDPE in the presence of 7 chalcone compounds is presented. The application of zero order or first order treatment to the experimental date obtained for stabilized LDPE has revealed that the depletion of antioxidant is a first order process. The comparison of the most efficient member of chalcone series and some commercial phenolic antioxidants has provided the following sequence for the prevention of oxidation: ETANOX - 330 > D 4 > IRGANOX -1076 > CYANOX - 2246 > TOPANOL - QC > > purified LDPE.
