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 ] D4 ] IRGANOX – 1076 ] CYANOX – 2246 ] TOPANOL – OC ]] purified LDPE

Keywords: LDPE; chalcones; thermal degradation; chemiluminescence
