  • Process for graft polymerization on surfaces of preformed substates to modify surface properties
    Patent number: 5805264
    Abstract: The invention relates to a process for modifying the surface characteristics of a preformed polymer substrate to impart altered properties thereto by graft polymerization on the substrate which includes: placing the polymer substrate in a plasma to form free radicals on the substrate; contacting the substrate having free radicals with oxygen to form hydroperoxy groups on the surface of the substrate; and graft polymerizing an ethylenically unsaturated monomer onto the surface of the polymer substrate.
