摘　　要：用过氧化二异丙苯(DCP)和偶氮二异丁腈(AIBN)为引发剂在合适的丙酮或四氢呋喃中将α 甲基丙烯酸接枝共聚到ABS上,通过红外光谱对接枝物进行定性的表征。通过滴定法对接枝率和接枝效率等的表征研究单体浓度、引发剂浓度和种类以及反应温度和时间等条件对接枝的影响。The solution graft copolymerization of α-methacrylic acid onto ABS was studied.The copolymerization was confirmed by infrared spectra and the grafting degree and grafting efficiency were measured by titration.The influences of solvent,kinds and concentration of intiator,concentration of monomer,reaction time and temperature were investigated in terms of grafting degree and grafting efficiency.
