Abstract :In our previous study, we prepared blends of low density polyethylene (LDPE) with semiconductor polymer, poly (1-amino-2-hydroxynaphthalene-4-sulfonic acid) (PANSA), in different mixing ratios. In that study, the findings on some physical and chemical properties of the blends prepared were also presented. In this study, it was aimed to investigate the thermal decomposition kinetics of these prepared blends. For this purpose, thermograms of PANSA doped LDPE blends at four different heating rates were obtained. With the addition of PANSA into LDPE, it was observed that the initial decomposition temperature and maximum decomposition temperature of LDPE increased. Thermal decomposition kinetics of blends were performed using the integral isoconversional methods (Kissinger, Kim-Park (KP), Tang, Kissenger-Akahira-Sunose (KAS) and Flynn-Wall-Ozawa (FWO)) in addition to differential isoconversional method (Friedman method). Thermal decomposition mechanism for blends was proposed with the help of master plot curves.
Keywords : Low density polyethylene, solid state decomposition kinetic
