摘　　要：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.The polyurethane emulsion was prepared by introducing carboxylic groups into urethane chains, and its rheology was investigated with rotation viscosimeter.
