Notizen: [Auszug] MEASUREMENTS by several workers have shown that the principal gaseous products produced when cellulose is irradiated in vacuum or in an inert atmosphere are hydrogen, carbon monoxide and carbon dioxide13. In all cases irradiations have been carried out in sealed tubes at a limited number of high ...

Notizen: Appreciable quantities of 4-vinyl pyridine and acrylamide have been grafted to nylon 6.6 by decomposing in their presence the peroxides and hydroperoxides formed on irradiating the polymer in air with γ-rays. The kinetics of the grafting process is interpreted in terms of a diffusion of the monomer into the nylon. The enhanced dyeing of the amine grafts and the lowering of the surface resistance of the graft by quaternization with dimethylsulfate are also reported.
