Abstract


Grafting reactions of glycidylmethacrylate on polyethylene were carried out in a Brabender internal mixer with capacity of 50 ml. There are strong and sharp peak in the PE-g-GMA IR spectra at about 1730 cm-1corresponding to carbonyl group (C=O) and at 850 và 910 cm-1corresponding epoxy group, but these peaks have not seen in neat PE spectra. The parameters of process condition were selected to achieve the highest grafting content: the temperature at 185oC, rotor speed of 40 rpm for 11 min. The received PE-g-GMA possessed: grafting content 1.705 wt.%, melt flow index 5.27 g/10 min and contact angle  45.21o.
