摘要
The pyrolysis of polyvinyl chloride (PVC) w as examined with a thermal gravimetric analyzer (TGA).The experiments were done over the temperature range of room temperature to 1?000?℃ at three heating r ates of 10, 20 and 50?℃/min under nitrogen atmosphere. The results indicate t hat the entire process of PVC pyrolysis consists of three distinct stages. In t his paper the pyrolysis of PVC was modeled by three independent reactions. The corresponding parameters such as activation energy, pre-exponential factor, and reaction order were determined. The kinetic model, composed of three independe nt and consecutive reactions, gives good agreement with the experimental results .
