| 摘 要： | 本文研究了两个系列的热塑型聚氨酯—聚醚酯氨(ET)和聚酯氨酯(ES)的结构形态与相分离程度,提出了一种确定硬段含量(W_h)的IR方法。与NMR法、投料比法比较,三者得到非常吻合的结果。此外本文还研究了W_h、M_(n·■)、拉伸及热历史对相分离程度的影响。

| Abstract: | The structure morphology and degree of Phase segregation for two series of thermoplastic polyurethanes - polyether-urethanes and polyester-urethanes have studied in this word.we suggest that the wh may be calculated by using IR method, which can be in comformity with that methods of NMR and molar ratio. The effects of Wh, Mn.s, extension, hot history etc. to the degree of phase segregation have also investigated. |
