Abstract

The thermal decomposition of polyethylene was analyzed by dynamic and isothermal experiments. Dynamic runs with different heating rates, exposed surface and initial mass were carried out. Isothermal runs of different initial mass were also carried out. Several kinetic models were tested and the best fit to the experimental thermogravimetry curves was obtained with a model involving a surface zero-order reaction.

    The dehydrochlorination of the polymer and the formation of conjugated double bonds happen in the first step. The second step includes the formation of low concentrations of hydrocarbons with linear or cyclic structures and the polymer’s continuous degradation [48]. The TG plots for polymer casing samples were smooth with single DTG curves and close to 100% weight loss at 600 °C.
