Study on the Recovery of High Density Polyethylene by Melt Grafting of Butyl acrylate
Butyl acrylate grafted recycle high density polyethylene(RHDPE-g-BA)was prep-ared by melt reaction extruding.By regulating the molten grafting temperature,Screw rotation speed,butyl acrylate dosage,initiator(DCP)dosage and other conditions,the effects of these factors on the grafting yield were studied.The product was characterized qualitatively and quantitatively by infrared spectroscopy(FTIR).Experimental results show that grafting products with a grafting yield of 3.27%can be obtained under appropriate conditions.
