| 摘 要： | 采用一步法将偏苯三酸酐、乙二胺、乙二醇(或丁二醇)与聚四氢呋喃(相对分子质量1000)经熔融缩聚得到一系列不同软、硬段比例的聚酯酰亚胺醚热塑性弹性体。利用乌式黏度计和显微熔点仪测试了共聚物的特性黏数和熔点。将聚合物真空干燥后进行熔融纺丝、拉伸和热定形,测定了纤维样品的纤度、断裂强度、断裂伸长和回弹率。

| Abstract: | A series of poly(ester-imide-ether) thermoplastic elastomers with different block ratio based on 1,2,4-benzenetricarboxylic,ethylenediamine,ethylene glycol(butanediol)and PTMG 1 000 were synthesized by a one-step method following a general method of formation for poly(ether-ester).Then,the copolymers were spun in a simple spinning machine.Inherent viscosity(η]) and melting point(Tm) of the block copolymers were measured by Ubbelodhe viscosimeter and microscope.Properties of the fiber such as denier,breaking strength,breaking elongation and elasticity were also measured. |

| Keywords: | block copolymer thermoplastic elastomer poly(ether-ester) elastic fiber |
