<p>Improved medical devices and instruments prepared by an improved method of producing hydrophilic, gamma-irradiation induced polymerized and chemically grafted coatings on plastic surfaces of articles adapted for contacting living tissue, the improvement comprising carrying out the graft polymerization in an aqueous solution under specific combinations of the following conditions: (a) monomer concentration in the range of from about 0.1 % to about 50 %, by weight; (b) total gamma dose in the range of from about 0.001 to less than about 0.50 Mrad; and (c) gamma dose rate in the range of from above about 2,500 to about 108 rads/minute.</p> |
