Abstract
Abstract Conductive moulding compositions comprise a vinyl chloride-vinyl ether copolymer which contains as comonomer a vinyl ether having the structural formula: wherein R represents an alkyl, haloalkyl, aryl or haloaryl radical having 1 to 18 carbon atoms, conductive carbon black particles, a stabilizer component, a lubricant component, and a plasticizer and processing aid component.
