Abstract: The research progress of the thermal degradation of polyether is reviewed. The thermal degradation products of polyether in the absence or presence of oxygen are presented. The thermal degradation mechanisms of polyether in the absence or presence of oxygen，the factors affecting thermal stability and the thermal degradation kinetics of polyether are discussed.
