采用热分析技术研究了聚偏氟乙烯-三氟氯乙烯共聚物（PVDF-CTFE）作为高能材料（HEMs）复合材料专用粘结剂的热行为。在空气和N2气氛下对聚（VDF-CTFE）共聚物进行了非等温热重分析。热重分析结果表明，聚（VDF-CTFE）共聚物在空气中比在N2气氛中降解温度低。在导数曲线中，存在单个最大降解峰（Tmax），表明所有样品的聚（VDF-CTFE）共聚物的一个阶段降解。用差示扫描量热法（DSC）测定了共聚物的玻璃化转变温度（Tg）和热降解温度（Td）。采用非等温Kissinger动力学方法和DSC方法研究了聚（VDF-CTFE）共聚物的热降解动力学参数。聚（VDF-CTFE）共聚物的热降解活化能在218-278 kJ/mol范围内。© 2012 Wiley Periodicals，Inc.

This article describes a study on thermal behavior of poly(vinylidene fluoride-chlorotrifluoroetheylene) [poly(VDF-CTFE)] copolymers as polymeric binders of specific interest for high energy materials (HEMs) composites by thermal analytical techniques. The non-isothermal thermogravimetry (TG) for poly (VDF-CTFE) copolymers was recorded in air and N2 atmospheres. The results of TG thermograms show that poly(VDF-CTFE) copolymers get degrade at lower temperature when in air than in N2 atmosphere. In the derivative curve, there was single maximum degradation peak (Tmax) indicating one-stage degradation of poly(VDF-CTFE) copolymers for all the samples. The other thermal properties such as glass transition temperature (Tg) and degradation temperature (Td) for poly(VDF-CTFE) copolymers were measured by employing differential scanning calorimeter (DSC) technique. The kinetic parameters related to thermal degradation of poly(VDF-CTFE) copolymers were investigated through non-isothermal Kissinger kinetic method using DSC method. The activation energies for thermal degradation of poly(VDF-CTFE) copolymers were found in a range of 218–278 kJ/mol. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
