Summary

Conditions of formation and stability of „frost effect” on layer of polystyrene with a very thin surface film prepared by crosslinking in an electric discharge were studied for different starting electric potentials of the surface. It was found that during the rise of the temperature of the sample the surface potential falls and a stable frost exists in a certain temperature interval. The explanation of the observed phenomena is based on Cressman's expression for electrocapillar effect and on effects connected with dilatation of the basic layer and artificial film on its surface.
