Abstract

This invention concerns non-porous, polymeric articles having active properties, and methods for producing such articles. Plastic, rubber, or other natural and synthetic polymeric articles are provided with active chemical and/or physical properties, such as, antibacterial, antifungal, pesticidal, insecticidal, animal repellent, odorous, antistatic, electrically conductive or other properties or combinations of properties, by applying to a surface of the article selected activating agents which are capable of migrating or moving throughout the body of the article to impart an effective level of activity throughout the article and/or on a surface other than the one to which the activating agents have been applied.
