Abstract
The eff ect of thermal oxidative aging on the structure and properties of polysulfones PSF-190 (Institute of Plastics JSC, Russia) and Udel P1700 (Solvay Specialty Polymers, Belgium) has been studied. The shelf life of the selected grades of polysulfones has been predicted. The diff erence in the course of the low-temperature thermo-oxidative aging process for PSF-190 and Udel P1700 is shown. It was found that the main changes in such characteristics as density, tensile yield stress, elongation at break occur during the fi rst 250 hours of thermo-oxidative aging. The value of the specifi c volume electrical resistance of polysulfones does not change under the infl uence of temperature and time under conditions of low-temperature thermo-oxidative aging.
