Abstract

Thermoplastic pellets are provided having electric conductivity properties in molded articles produced therefrom. The pellets have a thermoplastic resin matrix having incorporated therein a multitude of flexible conductive fibers made from an organic polymer containing a conductive component. Upon processing the pellets under the action of heat into a molded article, conductivity is achieved without adversely affecting the fibers and their ability to impart conductivity to the molded article.
