The temperature dependences of optical birefringence δ(Δn) for the principal cuts of [N(CH_{3})_{4}]_{2}CuCl_{4} crystals are measured. On the basis of the obtained experimental and theoretical data the anomalous behavior of physical parameters in conditions of the "viscous" interaction of the modulated structure with mobile defects in the incommensurate phase is explained.
