| Abstract: | The study of microphase separation is very important to the promotion of the properties of thermoplastic polyurethane elastomers, and it has been found that the degree of microphase separation of the elastomers has direct influence on its properties such as thermal property, mechanical property and so on. The theory of Krouse is comparatively suitable to the study of (A－B)n polymer. This paper makes a review of the theories of such microphase separation, the influencing factors and effects on the properties of the elastomers as well as the latest development in the study of microphase separation. |
