Conductive polyurethane foam compositions containing tetralyanoethylene and method

摘要

An electrically conductive polyurethane foam product is prepared by the in situ combination of polyurethane-forming reactants and an effective amount of a charge transfer agent selected from the group consisting of tetracyanoethylene (TCNE), picric acid and analogs thereof, for lowering electrical resistance of the foam product to less than 1x1012 ohms. In a preferred embodiment, the conductive foam product is reticulated to a void volume of more than 80% after completion of the foam forming reaction.
