摘　　要：以十二烷基硫酸钠为乳化剂、过硫酸钾为引发剂,通过乳液聚合,合成了苯乙烯-丙烯腈-N-苯基马来酰亚胺三元共聚物(St-AN-PMI),并考察了各单体配比、乳化剂浓度、引发剂浓度等对聚合反应和最后产物的影响。发现该共聚物中PMI的含量是决定其性质的重要因素,而聚合时合适的乳化剂浓度和引发剂浓度分别为13～15mmol/L和1.8～2.4mmol/L。Styrene/Acrylonitrile/N-Phenlymaleimide emulsion copolymerization was studied using sodium dodecyl sulfate as emulsifier and potas- sium persulphate as initiator.The effects of monomers ratio,emulsifier and initiator concentration on the polyresction and the product were investigat ed.It showed that the PMI content in the copolymer is important to the character of the copolymer,and for the copolymerization,the suitable reaction condition were:the emulsifier 13-15 mmol/L and the initiator 1.8～2.4 mmol/L.
