Grafting of acrylic acid (AAc) and acrylamide (AAm) onto preirradiated PP film was performed in aqueous solution of AAc and AAm, respectively. Electron beam accelerator was used as irradiation source. The effect of ferrous sulfate, sodium nitrate, methanol and glucose on the degree of grafting was demonstrated. The function of the different additives was compared by the grafting of different monomers (AAc and AAm). The results show that the four of these additives are elective on the grafting of AAc. Only two of these additives, ferrous sulfate and methanol were effective on the grafting of AAm.
