摘要
The thermal degradation kinetics of chlorinated natural rubber(CNR) at constant heating rate has been studied. The results indicate that the thermal degradation of CNR is a one step reaction and the degradation temperature is directly propotional to the heating rate, but the thermal degradation rate is less affected by the heating rate. The main reaction in thermal degradation is dehydrochlorination with an activation energy closing to that of the dehydrochlorination of PVC.
