THE KINETICS AND MECHANISM OF PYROLYSIS OF POLYCHLOROTRIFLUOROETHYLENE
聚三氟氯乙烯的热裂解动力学和机理的研究

The pyrolytic process of polyehlorotrifluoroethylene (PCTFE) in air was studied by using TG-DTG methos. The kinetic parameters were obtained by using the various kinetic approaches and the results were applied in order to evaluate the various kinetic theories and explain the variation of the activation energy during the pyrolytie process in the extent of 5-95% pyrolytie degree. The random pyrolytic mechanism was proposed according to the relations between the pyrolytie extent and rate of pyrolysis. We seccessfully explained the structures of pyrolytic products of PCTFE which ap-peared in recent literatures,and we also verified the experienced equation of bond dissociation energy proposed by Errede is inappropriate to PCTFE at least.
