Molded polyurethane articles having improved flex modulus and impact strength are produced by subjecting a polyurethane-forming reaction mixture which has been introduced into a mold to a static electric field. The static electric field must have a field strength which is less than the dielectric strength of the polyurethane being produced but sufficiently strong to align the hard segment dipoles of the polyurethane.
