Film samples were prepared by irradiating a polyethylene (PE) film immersed in a methanol solution of methacrylic acid by means of a 300- or 3000-C Co/sup 60/ source. Results indicated that the initial grafting occurred mainly at the surface, which in turn served as the matrix for further grafting. The weight of the PE grafted increased almost linearly vs time. The increase in the grafting rate was due to the gel effect on the swollen film surface layer. The amourt of polymethacrylic acid grafted in benzene-methanol system was greater than in methanol. The factors affecting the graft copolymers such as the film thickness, monomer concentration, dosage rate, solvent component, and the initial grafting rate are described. The electric surface resistance of the grafted film was also measured. (OID)
