چکیده
|
The graft copolymerization of maleiv anhydride (mah) onto high density polyethylene was investigated using benzyl peroxide (bpo) as an initiator and p-xylene as a solvent media. the effect of different parameters such as reaction time, reaction temperature, maleic anhydride (mah) and initiator (bpo) concentration were studied and discussed. the maximum grafting degree (1.37%) and percentage yield (72%) has been observed at mah concentration 1.02×10^-3 mol/l and bpo concentration 2.064×10^-4 mol/l for the reaction time 4 hrs. proof of grafting was also established by weight increasing, titration and ftir spectrum
