Summary:A process is disclosed for making an electrically conductive polyurethane elastomer from a polyether polyol prepolymer by blending an isocyanate terminated polyalkyleneether polyol prepolymer, preferably TDI and MDI terminated polyalkyleneether polyol, with conductive metallic salts such as CuCl2 dispersed in a prepolymer-miscible carrier, preferably tri(betachloropropyl)phosphate, thus providing a cured polymer with good conductivity while retaining its performance properties.
