Abstract

The pyrolysis kinetics of styrene-butadiene rubber (SBR) was studied by the kinetic model which accounts for the thermal degradation of polymer at any time. The kinetic analysis was performed by a conventional nonisothermal thermogravimetric (TG) technique at several heating rates between 10 and 50 K/min in a nitrogen atmosphere. To verify the effectiveness of the kinetic analysis method used in this work, the kinetic analysis results were compared with those of various analytical methods. The TG data were also compared with values calculated by using the kinetic parameters obtained from this work. It was found that the kinetic analysis method used in this work gave the reliable kinetic parameters of SBR pyrolysis.
