Resumo
Grafting of styrene on polyethylene was carried out as a preliminary study. The experiments covered a range
from 5 to 20 kGy and intended to evaluate the absorbed dose that led to the best degree of grafting (DOG) under
industrial dose rate. PE films 0,065 mm thick were exposed several times to radiation at room temperature and
nitrogen atmosphere. The films were immersed in the solution content styrene/solvent then irradiated (5 to 20
kGy) dose. As an exploratory experiment, styrene grafting was gravimetrically evaluated and characterized by
infrared spectroscopy (FTIR).The degree of grafting ( DOG) was calculated. Concentrations of methanol/
Styrene at the rate of 80:20 were favorable at low dose of 10 kGy. In presence of acid, best result was achieved
at 15 kGy in the range of 5 to 20 kGy.
