Grafted rubber films were prepared by mixing various proportions of acrylamide with natural rubber latex (NRL) with varying proportions by gamma radiation from Co-60 source at room temperature. Tensile strength, tear strength, elongation at break, permanent set, and swelling ratio, gel content and degree of grafting were measured. Tensile strength, tear strength, gel content and degree of grafting were found increasing with absorbed dose, as well as the proportion of monomer concentration and the optimum dose was found 12 kGy from the results. Elongation at break, permanent set, and swelling ratio of grafted rubber decreases with increase in absorbed dose, as well as proportion of grafted rubber.
