In this work the mixed problem for the forth order polylinear pseudohyperbolic equations is considered, when some coefficients are sufficiently smooth functions and some have bounded variations. The definition of weak solution is introduced. The theorem of existence and uniqueness of weak solution of the mixed problem.
