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.
