  • Patent number: 4317265
    Abstract: Electrically conductive elastomers are prepared by adding polyfunctional tertiary amine compounds to halogenated polymers. The resulting elastomers have resistivities in the range that makes them suitable as conductors for many electrical and electrostatic applications. These ranges are generally in the area of 1.times.10.sup.3 to 1.times.10.sup.7 ohm cm as measured by the methods of ASTM 257. A preferred elastomer is prepared by adding a polyfunctional tertiary amine such as N,N,N',N' tetramethyl-1,3-butanediamine to polychloroprene prior to vulcanizing under conventional vulcanization conditions. The resulting elastomers possess useful electrical conductivity, as well as the desirable physical and chemical properties of conventional elastomers. A roller for current-assisted printing or electrostatic-assisted printing having an external surface layer comprised of the novel electrically conductive elastomer is described.
