Abstract:
A process for adhering high nitrile resins onto a plastic material. The process comprises the steps of selecting a high nitrile resin having a nitrile content of at least about 60 percent by weight and prepared by the copolymerization of an olefinically unsaturated monovinyl nitrile and a monovinyl monomer copolymerizable therewith in the presence of a conjugated diene rubber, preparing a solution comprising from about one to 70 percent by weight of the high nitrile resin in a photopolymerizable solvent comprising from about 30 to 99 percent by weight of the solution and from about 0. 1 to 10 percent by weight of a photoinitiator with an attendant decrease in one or both of the high nitrile resin and the photopolymerizable solvent to provide 100 percent by weight of the solution, subjecting the surface of the plastic material to a reactive gas plasma, said reactive gases being selected from the group consisting of water, oxygen, hydrogen and combinations thereof to modify the surface, applying the solution onto the modified plastic surface and, curing the high nitrile resin and photopolymerizable solvent by irradiation to form a tack free protective coating highly adherent to the plastic surface.
