S>Polyvinyl alcohol film pretreated with water was irradiated in styrene with Co/sup 60/ gamma -ray. Then the graft polymerization of styrene to polyvinyl alcohol film proceeded with the irradiation. The grafted flim expanded almost evenly to the three dimensional directions. Styrene grafted polyvinyl alcohol film was cut into small pieces. Using those test pieces, specific gravity, degree of sweliing in water and benzene, heat plasticity, etc., were measured. It was found that there was little difference in the properties of the inner layer and the surface layer of the film. This fact indicates that graft copolymerization would proceed homogenously in the outer and inner parts of films except extremely thick ones. (auth)
