INFRARED SPECTROSCOPIC STUDIES OF GRAFTED CELLULOSE,
ATOMIC ENERGY OF CANADA LTD CHALK RIVER (ONTARIO)
New techniques have been developed for grafting monomers such as styrene and methyl methacrylate onto cotton fabrics and paper under the influence of gamma radiation. The products have vastly improved properties. The mechanisms of the grafting reaction, the probable active sites and the quality of the products have been studied at various stages by infrared spectroscopic techniques. Such studies have made it possible to follow the reactions and thus obtain desired properties. Spectra of the deuterated grafted products revealed that grafting takes place at the free and intermolecular hydrogen bonded regions. A possible reaction mechanism indicating the role of short lived and long lived free radicals is discussed. A structure of the grafted network has been proposed. Author
