We construct unitary partial-wave amplitudes for longitudinal WW scattering from general requirements of scalar dominance and the low-energy theorem of broken chiral symmetry. The amplitude is uniquely determined by specifying the mass of the scalar particle. For small masses, the amplitude in the minimal standard model is reproduced. For small masses above 1 TeV, the amplitude shows saturation behavior above the mass, and the scattering cross section is a few times larger than the extrapolation of the low-energy theorem.
