摘　　要：丙烯腈-丁二烯-苯乙烯三元共聚物(ABS)接枝聚合使用由甲醛次硫酸钠(SFS)、乙二胺四乙酸四钠(EDTA-4Na)和硫酸亚铁(FES)组成的还原剂时,氧化剂、还原剂以及接枝单体的不同加入方式对反应速率和接枝过程都有较大影响。采用“预补/全程连续”方式加入还原剂,连续滴加方式加入氧化剂和接枝单体,能够实现对整个反应阶段引发剂分解产生自由基的速率的精准调控,改善接枝效果,提升粉料的增韧效率。When a reductant composed of sodium formaldehyde sulfite(SFS),tetrasodium ethylenediaminetetraacetic acid(EDTA-4Na),and ferrous sulfate(FES)was applied in the graft polymerization of acrylonitrile-butadiene-styrene terpolymer(ABS),the different addition methods of oxidants,reductants,and grafting monomers have a significant impact on the reaction rate and grafting process.By adding reductants in a"pre-supplementary or whole continuous"manner,and adding oxidants and grafting monomers in a continuous drip manner,the precise regulation of the decomposition rate of the initiator to produce free radicals during the reaction can be achieved,improving the grafting effect and enhancing the toughening efficiency of the powder.
