Abstract Ethyl acrylate (EA), Vinyl imidazole (VI), and their binary mixture have been copolymerized onto rayon in aqueous medium by mutual method using γ‐radiation. The graft yield has determined as a function of different reaction parameters such total dose, concentration vinyl monomers, amount water. Effect surfactant (1‐octane sulfonic acid, sodium salt) studied on the percentage grafting EA, VI, (EA + VI). A plausible mechanism suggested to explain observed behavior grafting. Water retention moisture regain grafted film was at appropriate relative humidity. copolymers characterized IR spectroscopy scanning electron microscopic methods. © 2008 Wiley Periodicals, Inc.
