| Abstract: | The relation between structures and properties of poly-urethane are investigated by modern physical and chemical methods. The results obtained are as follows: the effects of the content of self - crosslinking agent on the properties of polyurethane, i. e., dispersion stability, dynamical viscoelasticity and mechanical properties are discussed. It is found that the optimum molar ratio of epichlorohydrin and diethylenetriamine is 1:2. A moisture - permeable water - proof urethane coated fabrics based on the polyurethane dispersion is prepared and some basic tests are taken. |
