Abstract: In this paper, the aqueous polyurethane anionomer dispersion (APUAD) was synthesized and the diameter of micelle of APUADwas measured by dynamic light scattering method. The results showed that the diameter of the micelle greatly depends on the number of the water-soluble group on the polyurethane, the flexibility and the hydrophobic/hydrophilic ratio of the main chain of the polyurethane. The phase separation was observed in the micelle by TEM.

Key words: Polyurethane, Aqueous dispersion, Dynamic light scattering, Micelle
