摘　　要：本文采用热重法(TG)研究了偏氟乙烯—六氟丙烯二元共聚弹性体(氟橡胶—26)的热降解动力学,结果表明:氟橡胶—26的热降解按二个热失重阶段进行,计算了它在空气、氯气气氛中二个热失重阶段的热降解反应级数、热降解活化能和频率因子。The kinetics of thermal degradation of vinylidene fluorde-hexafluoropropylene eopolymet was studied by dynamic thermogravimetry. It is noted there are two weight loss steps in the dynamic TG curves. Both in air and nitrogen the values of degradation reaction order(n), activation energy(Ea) and frequency factor (lnA)were obtained in two weitht loss steps.
