Single- and multilayered laminated nylon-6 films were grafted with acrylamide (AM) using the electron-beam preirradiation technique. Very high grafting yields were obtained within short time periods. Grafting onto single films was shown to proceed via diffusion free pseudo zero-order kinetics. Grafting onto multilayered films was diffusion controlled. Scanning electron microscope measurements indicate uniform grafting of single-film membranes and asymmetric grafting of membranes prepared by grafting onto multilayered films. The permeability of grafted membranes to a number of permeants was found to increase with extent of grafting. The specific permeability to both water and solutes exceeded that of the dialysis grade cellophane at 500% graft. The selectivity of grafted films towards various solutes had also been found to be higher than that of cellophane.
