Polytetrafluoroethylene carnot be dyed by the usual methods. However, if a dyeable polymer is deposited on the Teflon foil, a foil is obtained which retains the good characteristics of Teflon and can be dyed in various dye baths. Such a dyeable foil can be deposited on Teflon by graft polymerization with a suitable monomer after irradiation with a 220-kv, 15 mamp x-ray tube or the gamma rays from a 60-c Co/sup 60/ source. The following monomers were used: styrol, methyl methacrylate, vinyl acetate, and vinyl pyridine. Vinyl acetate requires the least irradiation and provides the best dyeability. The shade and intensity of the color depend on (a) the percentage of grafted copolymer, (b) the thickness, (c) the time of immersion in the dyeing bath, and (d) the temperature of the dyeing process.
