The polyurethane emulsion was prepared by introducing carboxylic groups into urethane chains, and its rheology was investigated with rotation viscosimeter. The results of rheology showed that the polyether-urethanc emulsion exhibited the character of Newtonian liquid. The viscosity and stability of the polyurethane emulsion depended on the temperature and carboxylic group content.

Key words: Polyurthane, Emulsion, Rheology, Newtonian liquid
