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.
Claims9
A composition comprising at least one cyclic olefin, at least one olefin metathesis catalyst, and at least one in-mold coating adhesion compound.
A method of in-mold coating a ROMP polymer comprising:
- providing a paint;
- applying the paint to a mold surface to form a painted mold surface;
- providing an optional primer;
- applying the optional primer to the painted mold surface;
- contacting the painted 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 effective to polymerize the resin composition.
(canceled)
An article of manufacture comprising an in-mold coated ROMP polymer, wherein the in-mold coated ROMP polymer comprises a resin composition comprising at least one cyclic olefin, at least one olefin metathesis catalyst, and at least one in-mold coating adhesion compound.
