Abstract:

 The prerequisite of covering of aluminum hydrous oxide, obtained by the hydrolysis of acidic alumimum salts in the present of urea, on pre-existing spheric polystyrene particles is that surface of pre-existing particles must be modified by anionic surfactants. Meanwhile, modifiers also accelerate the hydrolysis of aluminum salt, which will induce independent nucleation of aluminum hydrous oxide. Therefore, in order to prevent the formation of aluminum hydrous oxide particles, the amount of surface modifier should be correctly contolled.
