Composite articles and method for their preparation.
A method of making an integrally molded composite article composed of a ring-opened polynorbornene matrix and a compatibilized laminate and/or core components is disclosed. Laminate and/or core components that have low adhesion to polynorbornene or that interfere with the ring-opening polymerization of norbornene monomers are compatibilized by coating at least a portion of their surface with an inert polymer coating. The polymer coating enhances adhesion and prevents the interaction of deleterious functionalities on the structural components with the reactive monomer catalyst solution.
