单体液滴

在阶段Ⅲ开始时就可以目视观察到单体液滴的消失。

The disappearance of monomer droplets at the onset of interval III can be observed visually .

实验结果表明：不同引发剂引发聚合反应中，单体液滴为主要的聚合场所。

The results showed that monomer droplets were the sites for polymerization with different initiator .

细乳液聚合成核场所是单体液滴，其液滴尺寸决定聚合机理与乳液稳定性。

As monomer droplet nucleation predominates during the miniemulsion polymerization , the droplet sizes determine both the reaction mechanisms and the stability of miniemulsion .

其基本思路是通过速冻过程，将传统O/W体系中的水相固化为冰，使单体液滴成为具有硬壁的微反应容器。

The basic idea is to freeze the aqueous phase of traditional O / W system to the ice , so that the monomer droplets change into micro reactor vessel with " hard wall " .

结果表明，二乙烯基苯从单体分散阶段即开始影响单体液滴的分散尺寸，加入DVB后，单体液滴尺寸变小，最终产物粒径变小。

The effect was found at the stage of monomer dispersion . Addition of DVB would result in much smaller size of monomer drops and thus the smaller resultant particles could be obtained .
