Abstract
The present invention relates to in-mold coating of a cyclic olefin polymer. More particularly, the present invention relates to methods and compositions for in-mold coating cyclic olefin polymers prepared by ring opening metathesis polymerization (ROMP) reactions and the manufacture of polymer articles via ROMP. Polymer products produced via the metathesis reactions of the invention may be utilized for a wide range of materials and composite applications. The invention has utility in the fields of polymer and material chemistry and manufacture.
Claims6
A method of in-mold coating a ROMP polymer comprising:
- providing a urethane-based paint;
- applying the urethane-based paint to a mold surface to form a painted mold surface;
- providing a urethane-based primer;
- applying the urethane-based primer to the painted mold surface;
- contacting the painted and primed mold surface with a resin composition comprising at least one cyclic olefin, at least one olefin metathesis catalyst, and at least one in-mold coating adhesion compound;
- and
- subjecting the resin composition to conditions to polymerize the resin composition forming an in-mold coated ROMP polymer,
- wherein the in-mold coated ROMP polymer comprises the polymerized resin composition and an adherent coating thereon, wherein the adherent coating is formed by the urethane-based paint and the urethane-based primer.
