In this study, we consider a rheological Pokrovski-Vinogradov model of the flows of solutions and melts of an incopressible viscoelastic polymeric medium for a flow in an infinite plane channel with perforated walls. we prove the linear Lyapunov instability of the base solution with a constant flow rate in a perturbation class, which is periodic with respect to the variable, changing along the channel wall.
