Abstract: Preirradiation Grafting styrene monomer on ETFE  film has been prepared. Research has been  performed by γ-ray radiation at various total dose from 2.5 - 12.5 kGy and various dose rate from 1.3 - 1.9 kGy/hour. Irradiated copolymer is then grafted by styrene monomer in various solvent: ethanol, 2-propanol, and toluene, various concentration from 20 - 70% volume, various temperature from 50 - 90oC, and various grafting time from 2 - 12 hours. The results showed that percent of grafting is increase with increase of total dose and decrease of  rate dose. The optimum experiment conditions are obtained at total dose 10 kGy, dose rate 1,9 kGy/hour, 2-propanol solvent, 40% volume styrene, 4 hours grafting time, and 70oC grafting temperature.
