Abstract
In this paper, several powdered dispersants and water-soluble polymer dispersants were used in preparing physical blowing microcapsules. The particle size, size distribution and shape of the microcapsules were observed by optical microscope and electron microscope respectively, and analyzed with digital picture analysis system. The results showed that either powdered or water-soluble polymeric dispersants had obvious effects on the particle size and size distribution of the physical blowing microcapsules.
