| Abstract: | polyurethane elastomers are a type of important thermoplastics elastomers, microphase separation can significantly affect on the properties. The influence factors, studying means, and characteristic methods of the polyurethane elastomers were elucidated. Accelerator for microphase separation and ionization can be used to improve the degree of the microphase separation and physical properties. Polyurethane elastomers have a wide application in the field of the composite solid propellants, a certain degree of microphase separation can increase the mechanical properties of the propellants. |
