摘要
利用无皂乳液聚合的方法合成了表面含有羧基的亚微米级聚(苯乙烯-共-丙烯酸)(P(S t-co-AA))微球。通过透射电镜观察发现,微球粒径分布均匀,呈现明显的单分散性。用X射线光电子能谱(XPS)验证了微球表面含有羧基,且表面羧基含量可以通过聚合时加入单体的量来调控。
Surface-carboxylic poly （styrene-co-acrylic） （P （St-co-AA） sub-micron spheres were prepared by soap-flee emulsion polymerization. The microspheres were observed by transmission electron microscope to be uniform and monodispersed in diameter. Through X-ray photoelectron spectroscopy （XPS）, the existence of carboxyl on the surface of the microspheres were validated and its＇ content was controllable by the amount of acrylic acid used in the polymerization.
