Low temperature kink excitations of self-dual Z(p) symmetric quantum chains are related to the mass gaps in the high temperature phase. It is shown that they provide the massless physical excitations of the intermediate phase. The numerically calculated kink spectrum is presented for chains of different lengths for p = 5, 7 and 9. The order-to-Coulomb transition is found to be of second order for p = 5 (v = 2.19) and of infinite order for p = 7 and 9.
