Abstract : This study was designed to obtain a better understanding of the thermal decomposition processes pertaining to three different step-growth polymers (Nylon 6, polyethylene terephthalate (PET), and polycarbonate). An intensive analytical study of thermal degradation has been carried out on these step-growth polymers. Further studies were conducted on the Nylon 6 polymer containing non-reactive halogen-based fire retardants. Prior to the degradation studies, each polymer was characterized by elemental analysis and infrared spectroscopy. Thermal analyses of samples were carried out using a Mettler Thermoanalyzer. The effects of heating rate and environment on the degradation processes of step-growth polymers were analyzed using thermal analysis techniques. jg
