Study on the Grafting of MAH on the EVA by Reactive Extrusion and Its Application in the System of LDPE/MH

The grafting of maleic anhydride(MAH) onto EVA has been studied by reactive extrusion.The effects of various parameters,such as DCP,MAH concentration and process condition on grafting ratio and melt index are studied.The results show that the grafting ratio will increase when the content of DCP and MAH increase,but the melt index will decrease in the same time.The effects of grafting ratio on mechanical property of the system are studied by adding the produced compatilizer to the LDPE/MH system.
