METHOD OF HYDROPHILIZING AND IMPARTING ANTI-FOG PROPERTIES TO HYDROPHOBIC, TRANSPARENT, POLYMERIC OBJECTS ADAPTED FOR USE AS OPTICAL AIDS COMPRISING SWELLING THE SURFACE OF A HYDROPHOBIC, TRANSPARENT, POLYMERIC OBJECT BY CONTACTING SAID OBJECT WITH AT LEAST ONE HYDROPHILIC MONOETHYLENICALLY UNSATURATED MONOMER AND THEREAFTER POLYMERIZING SAID MONOMER IN THE PRESENCE OF A POLYMERIZATION INITIATOR TO THEREBY FORM A HYDROPHILIC, POLYMERIC LAYER INTEGRALLY BONDED TO SAID HYDROPHOBIC POLYMER SURFACE. THESE MONOMERS ARE SELECTED FROM THE GROUP CONSISTING OF ETHYLENE GLYCOL METHACRYLATE, BUTYL METHACRYLATE, BENZYL METHACRYLATE, DIALKYL CARBONATE, ACRYLAMIDE, METHACRYLAMIDE, AND MIXTURES THEREOF. |
