AbstractAbstract
[en] It was studied the radiation grafting of N-vinyl pyrrolidone onto silicone rubber tubes by the simultaneous method in sup(60)Co source. The influence of monomer concentration, dose rate and irradiation dose on the grafting yield was observed. The water content increased with the grafting yield. (author)

AbstractAbstract
[en] The synthesis of a hydrogel having silicone rubber tubes as support was carried out through the radiation grafting technique. The best conditions for the grafting development were determined in relation to the monomer and inhibitor concentration, dose rate and irradiation dose. The addition of cupric ions in the process inhibited the acrylamide homo polymerization and enhanced the grafting yield. The water content in the grafted tubes characterized the hydrophilic property of the material. (author)

AbstractAbstract
[en] Modified polymeric substrates can be attained by graft polymerization techniques, involving either simultaneous irradiation or pre-irradiation method. In the pre-irradiation method the polymeric substrate is irradiated in the presence of atmospheric oxygen to form peroxide groups onto the substrate, which in contact with vinylic monomer initiates the graft polymerization. In this work, silastic tubes were irradiated in 60 Co source. The acrylamide monomer has hydrophilic properties and rapidly homo polymerizes. Certain concentration of cupric ions inhibits homo polymerization and permits the graft polymerization to occur. It was studied the irradiation time that varied from 24 to 360 h at the dose rate of 0.66 kGy/h; the reaction time up to 48 h; the reaction temperature from 37 to 80 0 C; the acrylamide concentration from 1 to 50% and the copper concentration in the range of 0,01 to 0,5 molar.
