Oxidative behavior of polymers by thermogravimetric analysis, differential thermal analysis and pressure differential scanning calorimetry

摘要: Abstract Oxidative behavior of commercial engineering plastics, polyolefins and elastomers has been evaluated by simultaneous thermogravimetric analysis (TGA)–differential thermal (DTA) pressure differential scanning calorimetry (PDSC). There is a good correlation between the measured stability PDSC in oxygen DTA/TGA air nitrogen for olefin polymers. The thermo-oxidative properties are reliable precise. Glass-filled Nylon 66 reinforced polypropylene were studied an oven at 300°C as function time Fourier transform infrared (FTIR) spectroscopy. mechanism oxidation was different these two Polyolefin delineated rapid carbonyl formation, while showed minimum FTIR. An interesting outcome this study that polyethylene have significantly high heats combustion. At temperatures pressures, it appears polymers can be used sources fuel.
