The generalized model of Kronig – Penny for polymer molecule as regular chain of  D⁰-centers in quantum wire, simulated by zero-range potentials, has been considered. Equations, which determine limits of impure zone, have been obtained. Possibility to control the impure zone width and the localized electron effective mass by variation of external magnetic field value, has been also demonstrated.
