摘要
利用沉淀聚合方法，自由基引发二乙烯基苯聚合，制备了具有较窄粒度分布的聚二乙烯基苯超细微粒，用扫描电镜对其表面形态和粒度进行了表征；红外光谱表明这种聚合物超微粒仍存在有较多未反应的悬吊双键，可以继续与其它功能基团进一步反应，且粒度均一可控。
The polydivinylbenzene particles with narrow size distribution were pre pared by radical precipitation polymerization The particle size distributionand the surface morphology were studied using SEM IR spectra showed that there existed some residual double bonds in the particles, which can react with other compounds without any special modification The particle size can easily be controlled according to the conversion
