TPU 是由刚性和柔性链段组成的二相形态结构。。 在根据特定目标控制TPU的化学基础原料之间的反应时,可以实现更大或更小的嵌段结构,并由柔性多元醇基团和刚性(有序)扩链剂的比例(分离)决定。扩链剂嵌段中的这种顺序是由于与相邻聚合物链的扩链剂嵌段的物理相互作用而发生的。这些相互作用是TPU弹性行为的节点。同时,...

TPU is short for thermoplastic polyurethane elastomer in Chinese. TPU is a polymer material formed by the common reaction and polymerization of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) and macromolecular polyol and low molecular polyol (chain extender...
A change in the morphology of the polyurethane was observed, which was caused by the change in molecular structure by the chemical modification. The high level of bond strength may be due to a combination of these phenomena.doi:10.1002/pen.10997M. Bräuer...
