Abstract

Process for the treatment of polymeric materials, especially to reduce the tendency of the synthetic polymeric material to attract dust, characterized in that it comprises the destruction, reduction or distribution of an electric charge trapped inside the material, which will reduce the external electric field caused by the trapped load.
