Abstract:
1. A method for producing a coated molded polymer article including the steps: a) providing a polymer A formed by radical polymerization of ethylenically unsaturated monomers which include b) providing a mold, molding surfaces of which are substantially free of surface functional groups capable of reacting to form covalent bonds with said pendant reactive groups of polymer A; c) providing at least a portion of the surface of the mold with a coating of polymer d) providing a liquid curable composition comprising a functional compound reactive with the reactive groups of polymer A, e) contacting said liquid curable composition with the mold whereby the composition is in contact with the coated portions of the mold surface, and f) curing the curable composition to form bulk polymer B under conditions such that reaction takes place between said functional compound and the reactive groups of polymer A to form a covalent bond linking polymer A to polymer B at least at the interface between the coating and bulk polymer B, g) and demolding the bulk polymer B with polymer A coating.
