ABSTRACT:
Surface properties of an article prepared from an organic polymer are improved by a method of irradiating the surface of the article in air with ultraviolet radiation in the range of about 830 to 1335 A. Apparatus for generating ultraviolet radiation includes a capacitor, an exciting electrode which coacts with at least one of two primary electrodes to produce an arc between the primary electrodes, switching and timing means for energizing the capacitor and means for limiting current between the exciting electrode and capacitor, and a source of ac voltage.
