摘要
讨论了不同结构的小二醇以及TPU中刚性链段分子对聚氨酯TPU性能的影响。结果表明,改变小二醇的结构和数量可以有效调节聚合物的硬度、模量、撕裂强度以及其他性能。二醇扩链剂是影响TPU物理性能的一个重要因素。
This paper discusses on the influence of the sub-diol with different structures and the molecules of the rigid segment in TPU on the performance of polyurethane TPU, changing the structure and the quantity of the sub-diol can effectively regulate the hardness, module,tear strength and other performances of the polymer, The diol chain-extension agent is an important factor influencing the physical performance of TPU.
