The momentum-space bosonization method of a Nambu and Jona-Lasinio type model with vector and axial-vector mesons is applied to ?? scattering. Unlike the case in earlier published papers, we obtain the ?? scattering amplitude using the linear and nonlinear realizations of chiral symmetry and fully t
