Annotation: The results of experimental study of polypropylene surface modification by pulsed electron beam in the forevacuum pressure range are presented. It is found out that under the irradiation by electron beam similarly oriented knolls and valleys are formed on the polypropylene surface. The degree of surface modification and its structure depend on the input power into the sample. Measurement of the surface wettability showed that the liquid droplet spreads mainly along the knolls and valleys.
