Abstract
The method and mechanism of radioinduced graft copolymerization of 4- vinyl pyridine to Terylene filament yarn fabric, polyacrylonitrile, and polyethylene are described. The best results are obtained when the dry fabric is irradiated in air and is followed by reacting 4-vinyl pyridine with the fabric in the absence of oxygen. The 4-vinyl pyridine is applied to the fabric as a 2% aqueous solution. Graphs are given showing the effect of temperature on the rate of grafting of 4-vinyl pyridine to Terylene at a dose of 1.5 Mrad and the effect of dose rate on grafting. Results show that dyeability and antistatic finish are improved by the irradiation process. (N.W.R.)
