Abstract

The aim of this research is to develop a new method for studying thermal degradation behavior of elastomers containing butadiene units by isothermal and anisothermal analysis. Accelerated aging such as isothermal thermogravimetry analysis shows that when BR, SBR and NBR elastomers are subjected to specific time and temperature condition in nitrogen atmosphere, an interchain reaction occurs. Experimental observations also show that thermal degradation mechanism of these elastomers depends on heating rate and time–temperature history. For these types of elastomers, the effect of time is similar to temperature and time–temperature superposition principle can be employed for studying the thermal degradation mechanism of elastomer containing butadiene units. © 2009 Wiley Periodicals, Inc.
