ABSTRACT:
Conductive elastomeric compositions consisting essentially of a blend of a copolyetherester having 45-85 weight percent of long chains and 15-55 weight percent of short chains and melting at at least 90.degree. C. with a conductive filler consisting of carbon black or a mixture of carbon black with graphite, the resistivity of such compositions being less than about 2 ohm.cm can be fabricated or cast into thin, self-supporting films or sheets. Articles made from these compositions find utility in electrical and electronic equipment, business machines, and in applications where good aging properties are important.
