Abstract
The procedure and the experimental results of a study on the dispersion of polytetrafluoroethylene (PTFE) in a vacuum by 0.1-2.5-keV electrons are rep orted. The time course of the multistage dispersion process was studied and its oscillatory modes occurring upon the evolution of volatile products we re described. Based on the analysis of the specific features of dispersion and the characteristic parameters of the process, it was concluded that ele ctron beam-assisted degradation of PTFE should be considered a thermal depo lymerization process induced by ionizing action of electrons.
