V-17419/+/CGV 1396 ABSTRACT PROCESS FOR THE ENCAPSULATION OF PREFORMED SUBSTRATES BY GRAFT COPOLYMERIZATION A process for encapsulating a preformed polymeric substrate comprises peroxidizing and hydroperoxidizing the surface of said preformed substrate using ozone and then carrying out a crosslinked graft copolymerization of selected ethylenically unsaturated monomers both on and surrounding (encapsulating) said substrate. Such encapsulation of substrates provides protective coatings, ablative coatings and, particularly, soft skirts for hard contact lenses.
