N2 - The critical behaviour of a one-dimensional kinetic Ising model with NN interaction and purely diffusive dynamics is solved exactly. At the ferromagnetic transition Tc = 0 the diffusion constant is found to vanish ≈ξ-3 corresponding to a dynamical exponent z = 5 in contrast to conventional theory, whereas the scaling function to lowest order in ξ-1 and q exhibits Ornstein-Zernike behaviour.
