ABSTRACT OF THE DISCLOSURE Polyvinyl halide compositions inherently interfere with the ring- opening polymerization of norbornene monomers. A method of making an integrally molded composite article composed of a ring-opened polynorbornene matrix and a polyvinyl halide lamina and/or a core component is disclosed. By removing certain components used in the manufacture and compounding of polyvinyl halide resins, a polyvinyl halide lamina can be integrally molded to a polynorbornene matrix via metathesis ring-opening polymerization of norbornene-type monomers.
