摘要：
A method for modifying the plastic surface of an article adapted for contacting living tissue by the gamma or electron beam irradiation induced chemical graft coating thereon of:(1) a neutral or ionic water-soluble, hydrophilic vinylic monomer or salt thereof;(2) a mixture of at least two of said monomers, or(3) a mixture of (1) or (2) with up to about 50%, by weight, based on the total monomer weight, of a member selected from the group consisting of N-vinylpyrrolidone, 2-hydroxyethyl-methacrylate, and mixtures thereof; so as to form a hydrophilic graft polymer coating on the surface.
