| Abstract: | The effects of R t value (the mol ratio of NCO group and all OH groups) and content of carboxyl on polyurethane emulsion were studied while the content of polyether glycol was fixed. The results showed that they had great effects on stability of polyurethane emulsion and water absorbed rate and mechanical properties of film. |
