摘要
采用国产聚醚砜(PES)树脂为原料,添加不同的增塑剂,在不同的实验条件下进行熔融法纺丝实验,并对其热性能、流变性、可纺性及纤维的力学性能进行了研究。通过对聚醚砜树脂的分子质量和增塑剂种类及含量进行调整,在适当的工艺条件下,该聚合物流动性有了明显改善,具有良好的熔融可纺性。其中以按100／20配比在PES-E中添加3#增塑剂的纺丝效果最好。
PES （Polyethersulfone） is a special polymer which is explorated recently, it is antiflaming, heat-stable and heat-plastic. In this paper, the melt-spinning of PES fiber was studied at different conditions. The PES resin is demestic with some kinds of plasticizing agents added. The thermal behavior, rheological property, spinnability and me- chanicle property of PES and its fiber were also studied. In results, the PES resin can be melt-spun successfully in suitable technics. Among those experiments, the PES - E with 3# plasticizing agent at 100/20 has the best spinnability.
