초록 ▼

A process for modifying the surface characteristics of a preformed polymeric substrate to impart hydrophilicity, hydrophobicity or other desired properties thereto comprises peroxidizing and hydroperoxidizing the surface of said preformed substrate using ozone, directing the subsequent graft polymerization of selected ethylenically unsaturated monomers essentially solely to the surface of said substrate to achieve the desired alteration of substrate surface characteristics while maintaining substrate structural integrity. Substrates so modified are useful in biomedical devices, semipermeable membranes, films, fibers and especially contact lenses.

대표청구항 ▼

A process for modifying the surface characteristics of a preformed polymer substrate to impart altered properties in respect to hydrophilicity, hydrophobicity, optics, transmissibility, dyeability or tintability, opacity, diffractability, wettability, bonding characertistics, oxygen permeability, lubricity, diffusibility or bactericidal properties thereto by graft polymerization on said substrate, having peroxy and hydroperoxy groups on said polymer, of an ethylenically unsaturated monomer, which comprises contacting the polymer substrate with a solution which is or contains a chain transfer agent to saturate or swell said polymer, said solution being insoluble in the perhalogenated liquid medium used subsequently during the ozonation step, to limit subsequent hydroperoxidation and peroxidation to the surface of said polymer, ozonating the saturated or swollen polymer with ozone dissolved in a perhalogenated liquid medium insoluble in the solution containing the chain transfer agent, and then graft polymerizing an ethylenically unsaturated monomer onto essentially only the surface of the polymer substrate.
