摘　　要：考察了甲基丙烯酸羟乙酯/丙烯酸甲酯接枝聚合炭黑的适宜制备条件和影响因素。通过红外光谱(FT-IR)、热失重分析(TGA)考察了接枝炭黑的表面结构和接枝情况,研究了接枝炭黑在水溶液中的吸光度。结果表明:用丙烯酸甲酯/甲基丙烯酸羟乙酯接枝改性后的炭黑在水溶液中具有良好的分散稳定性。The reaction conditions for preparation of hydroxyethyl methacrylate/methacrylate copolymers modified carbon black were investigated,and the influencing factors of the graft polymerization on carbon black surface were discussed as well.The composition and graft polymerization of grafted carbon black were characterized by infrared spectroscopy（FT-IR）and thermal gravimetric analysis（TGA）.The dispersion stability of grafted carbon black in aqueous solution was analyzed by spectrophotometer.The results showed that modified carbon black grafted with hydroxyethyl methacrylate/methacrylate copolymers was stable and well-dispersed in aqueous solution.
