【 摘 要 】

A series of UV-curable waterborne polyurethane with antioxidant CA (CWPU) were prepared successfully by FT-IR. The influence of CA on different properties of the CWPU emulsions and films was investigated using DLS, and DMA. The results indicated that with the increase of CA, the latex particle size increased. Meanwhile, all the films had the loss factor was≥0.3 spanning a temperature range of approximately 95°C, with a maximum value increased from 0.64 to 1.09, respectively. The CWPU films could be used as a coating for damping applications.
