The analytical description and numerical modelling of interphase interaction processes in layered metal - polymer composite materials are considered. Dynamics of physical processes in one-dimensional multilayered metal-polymer-polymer-metal structure taking into account adhesion interaction and size effects in thin films are studied by analytical description and numerical modeling in the framework of uniform mathematical formalism of the molecular kinetic approach. It is found, that change of density of the active centres in polymers and its distribution into the volume and at the interfaces are determined by mutual intermolecular influence of layers. Correlation of adhesive interaction decrease on the interphase border with the increase of thickness of a polymer layer is established at a high level of intermolecular interaction in separate layers of polymer. At the low level of interaction - the opposite effect is observed. The increase of activity of substrate surface results in significant decrease of cohesion durabilities of a contacting polymeric layer and to displacement of area of weak boundary layers to interphase border. It is shown, that the considered physical model of layered metal - polymeric structure adequately reflects the basic laws of the nonequilibrium physical processes proceeding on the interphase border, it allows to carry out an estimation of the basic relaxation characteristics of a material at creation of multicomponent composite systems on the basis of polymers.
