采用微通道乳化和后续聚合的方法制备了粒径分布较窄的聚二乙烯基苯微球。用两种微孔板分别制备了平均直径为9.2μm、变异系数为5.7%的大分子筛板和平均直径为3.4μm、变异系数为7.4%的小型分子筛。MS的直径可以由MC的大小控制。该方法简单，有利于合成粒径分布较窄的聚合物MS。
Polymeric divinylbenzene microspheres (MS) of narrow size distributions were prepared by microchannel (MC) emulsification and subsequent polymerization. Using two types of MC plates, large MS with 9.2 μm diameter on average and 5.7% coefficient of variation, as well as small MS with 3.4 μm diameter on average and 7.4% coefficient of variation were prepared. The MS diameter can be controlled by the size of the MC. This method is advantageous for synthesizing polymeric MS of narrow size distributions because of its simplicity.
