摘　　要：简单介绍了聚ε-己内酯型热塑性聚氨酯弹性体的合成工艺,研究了聚ε-己内酯分子量、硬段含量、n(—NCO)/n(—OH)和异氰酸酯结构对其性能的影响。结果表明,n(—NCO)/n(—OH)和异氰酸酯结构对热塑性聚氨酯弹性体的熔融指数、微相形态结构和物理机械性能有较大的影响。Some thermoplastic polyurethane elastomers based on potycaprolactone glycol （PCL）were prepared with one-step. The effects of soft segment molecule weight, hard segment content, n （-NCO）/ n （-OH） ratio,different diisocyanate structures on physical mechanical properties of TPUE were studied. It was found that different n （-NCO）/n （-OH）ratios and different diisoeyanate structures have a great effect on the melt index,the microphase morphology structure and physical property of TPUE.
