| 摘 要： | 以十二烷基硫酸钠为乳化剂,2,2-二甲氧基-2-苯基苯乙酮等为引发剂,在水中由紫外光引发苯乙烯(St)和甲基丙烯酸甲酯(MMA)进行乳液聚合,研究了引发剂种类及乳化剂用量对反应收率和微球粒径的影响,并与光引发分散聚合体系进行了比较。结果表明,乳液聚合速率大于分散聚合,由乳液聚合得到的P(St-co-MMA)微球的粒径均一,可控制在70～140 nm之间。

| Abstract: | P(St-co-MMA) microspheres were prepared by photoinitiated emulsion polymerization of styrene(St) with methyl methacrylate(MMA) in water using 2,2-dimethoxy-2-phenylacetophenone(BDK) and sodium dodecyl sulfate(SDS) as the initiator and emulsifier,respectively.The effects of initiator,amount of SDS on the yield and diameter of P(St-co-MMA) microspheres were studied,then compared with photoinitiated dispersion polymerization.The results showed that the rate of photoinitiated emulsion polymerization was faster than that photoinitiated dispersion polymerization,and the diameter of P(St-co-MMA) microspheres can be controlled in range from 70 to 140 nm. |
