Kinetics of Thermal Degradation of Acfylonitrile-Butadiene-Styrene Copolymer

Thermal degradation of polymer ABS was Studied by using the method of gravimetric analysis(TG,DTG).The Sestak's complex mechanism was used to do curve fitting,the computame results of kinetics parametcrs of activation energy E,preexponential A and the reaction degree have a good stability and repeatability.The superiority of the Sestak's mechanism to describe the ABS's degradation was also discussed.
