摘要：

Physical and mechanical properties of polyphenylenesulfidesulfone (PPSS) were measured and compared with those of other high performance sulfur containing amorphous polymers such as polyethersulfone (PES) and polysulfone (PSF). PPSS showed poorer toughness than PES and PSF, and the enthalpy relaxation behavior of PPSS was investigated using DSC in order to understand the brittle nature of PPSS. The rate of enthalpy relaxation of PPSS was found to be very high and the fast relaxation is probably responsible for the brittle nature of PPSS. Dynamic mechanical spectra of PPSS were also measured to supplement the understanding of the relaxation behavior.
