摘要/Abstract

摘要： 摘要:分析了国内外研究聚对苯噁二唑(POD)纤维的进展，针对POD的特点，引入磷系和卤系第三单体进行共聚，明显改善POD纤维的阻燃性，LOI可达30以上；详细探讨了凝固浴条件对POD纤维聚集态结构、表面形貌和力学性能的影响，证明40~50%的硫酸水溶液为最佳凝固浴浓度；通过与其他耐高温纤维各种性能的对比得出，POD纤维耐高温性能优于PPS、Nomex和Tanlon，具有较好的力学性能，耐化学腐蚀性和染色性，应用前景广泛。

Abstract: Abstract: The development of poly(phenylene-1,3,4-oxadiazoles) (POD) fibers in home and abroad were discussed. The functional monomers containing phosphorus or halogen were copolymerized with POD for improving the cyclization degree and flammability of POD fibers, whose LOI can be up to 30. The coagulating conditions had an influence on the aggregation state, surface and mechanical properties of POD fibers. Sulphuric acid solution of 40~50% concentration is the best coagulating agent. Compared with other heat resistant fibers, POD fibers have a better thermal stability than PPS, Nomex and Tanlon. Besides, the good combination of other performance, such as mechanical properties, chemical resistance and dyeing ability, enhances the application of POD fibers in many fields.
