A process for producing a hydrophilic coating on a polymer substrate comprising activating thepolymer substrate by exposure tomonochromatic, continuous UVradiation in the presence of oxygen and of a wavelength sufficientto provide hydroperoxide groupson the substrate; immersing theactivated substrate in a solutionof at least one hydrophilic groupcontaining vinyl monomer; andsubjecting the immersed, activated substrate to monochromatic, continuous UV radiation ofa wavelength sufficient to dissociate the hydroperoxide groups andinduce graft copolymerization ofthe vinyl monomer onto the substrate.
