| 摘 要： | 以苯乙烯为单体、二乙烯基苯（DVB）为交联剂，过氧化二苯甲酰（BPO）为引发剂研究了蒸馏沉淀聚合法制备聚合物微球过程中交联单体二乙烯苯的用量对单分散聚合物微球成球的影响。结果表明，增加二乙烯基苯的比例，即提高交联度有利于形成单分散的聚合物微球。

| Abstract: | Commercial divinylbenzene(DVB),used as crosslinker,was copolymerized with styrene(St)by distillation-precipitation polymerization with benzyl peroxide(BPO)as initiator in neat acetonitrile.The effect of DVB fraction on the formation of monodisperse polymer microspheres during the copolymerization was investigated.The results showed that increasing crosslinking degree is favorable to prepare monodisperse polymer microspheres. |
