摘要

在沉淀聚合中利用含无毒的乙酸溶剂合成出窄分散交联聚二乙烯基苯（PDVB-55）微球

用扫描电镜（SEM）对其表面形态和粒度进行了表征

结果显示PDVB-55微球均匀且互相分离

平均粒径是2.69μm.X射线光电能谱（XPS）分析表面化学组成显示

微球表面有大量残余双键.

Abstract

Acetonitrile

a substance harmful to human health

is the most commonly used solvent for the synthesis of cross-linked polymeric microspheres by precipitation polymerization.Here

the innoxious acetic acid has for the first time replaced acetonitrile as a solvent in the precipitation polymerization of narrow disperse crosslinked poly(divinylbenzene)(PDVB-55)microspheres.Scanning electron microscopy(SEM)results showed that the PDVB-55 particles were uniform and well separated

and the diameter was measured to be 2.69 μm.X-ray photoelectron spectroscopy(XPS)shows that there are significant amount of double bonds on the surface of the microspheres.
