【Abstract】 UV photo-grafting on high density polyethylene (HDPE) was performed by using methyl methacrylate (MMA). The graft copolymer of HDPE-g-MMA was confirmed by FT-IR and 1H-NMR spectra after purification. With copolymerization temperature, the grafting rate (G) increased. With copolymerization time, monomer concentration and sensitizer concentration, the grafting rate increased, and decreased after passing a maximum. The effect of the content of HDPE-g-MMA on HDPE/Sericite-tridymite-cristobalite (STC) system was investigated systematically. The results show that HDPE-g-MMA has obvious interface modifying effect on HDPE/STC system.更多还原
