| 摘 要： | 以甲基丙烯酰氧乙基三甲基氯化铵(MTC)为共聚单体,聚乙烯吡咯烷酮(PVP)为分散稳定剂,偶氮二异丁腈(AIBN)为引发剂,在去离子水和乙醇的介质中采用分散聚合的方法制备了微米级单分散聚苯乙烯(PS)微球.结果表明:MTC与PS发生共聚;AIBN及PVP用量对共聚微球的尺寸及尺寸分布有影响;共聚单体MTC的用量不影响共聚微球的尺寸分布;在苯乙烯用量为20 g,MTC用量为0.2～0.4 g时能得到表面非常光滑、无破损、无缺陷的共聚物微球,并且MTC的加入有利于无机粒子TiO2的包覆.

| Abstract: | Monodisperse copolymer microspheres were prepared by dispersion polymerization in ethanel/water medium using polyvinylpyrrolidone(PVP) as a steric stabilizer,2-(methacryloyl)ethyltrimethy lammonium chloride(MTC) as copolymer monomer and 2,2-azobisizobutyronitrile(AIBN) as an initiator.The results show that the copolymer structure synthesized was in accordance with the expectable structure.The influencing factors on the copolystyrene microspheres size and size distribution were investigated.The amount of ini... |
