聚-1,3,4-噁二唑纤维研究进展

Research progress of poly(1,3,4-oxadiazole)s fiber

介绍了聚-1,3,4-噁二唑(POD)的合成、改性、纺丝成形、后处理及耐老化等方面的研究进展。详述了采用一步法三阶段合成POD,并通过引入间苯二甲酸和对苯二甲酸进行共聚改性,得到的POD纤维在亲水性、抗静电性、染色性能等方面得到了改善;探讨了凝固浴条件对POD纤维结构与性能的影响,阐述了POD纤维的老化降解及防护问题。

The research progress in synthesis,modification,spinning process and after treatment of poly（1,3,4-oxadiazole）（POD） was introduced.POD was synthesized by one-step three-stages process and modified by introducing isophthalic acid and terephthalic acid via polymerization.The hydrophilicity,antistatic property and dyeing property of POD were improved.The effect of coagulation conditions on the structure and properties of POD fiber was studied.It was pointed that the aging property and stability of POD fiber would be the research focus in the future.
