Abstract. The effect of cold rolling of the isotropic and preliminary oriented polystyrene films on their properties has been investigated. It was found that the film modification by the cold rolling is necessary to conduct for only the isotropic films but not for the oriented ones. To achieve the optimal state of rolling and to reduce the side stresses at drawing, the process should be performed in several consecutive stages.

Key words: cold rolling, isotropic polystyrene films, oriented polystyrene films, mechanical parameters, optimal state of rolling.
