摘要
Abstract
The melt graft of maleic anhydride(MAH) onto cellulose acetate(CA) was studied. The grafting reaction was initiated by DCP in a twin screw extruder at 175 ~ 200 ℃. IR spectra showed that the grafting reaction had occurred. The effects of DCP and amount of MAH on the reaction were studied. The effects of MAH and its amounts on the thermal stability and rheologica) behavior of grafted CA were studied. The results showed that grafting rate was highest when the amounts of DCP was 0.4%. And the grafting rate was higher when the amount of MAH was higher. The thermal stability of CA-g-MAH was better than CA's. The melt viscosity of CA-g-MAH was lower and the MFR was higher.关键词
