| Abstract: | In this paper, a blending polyether-based polyurethane elastomer was synthesized by blending two polyethers and polyterahydrofuran. The effects of the blending ratio of the two polyethers on the microstructure, the mechanical properties of the polyurethane and the flow behaviors of the solution of the elastomer were also investigated. The results show that the addition of polyoxypropylene into the system can improve the processing behavior and enhance the low-temperature endurance of the elastomer. |
