一种共聚改性低缺陷对位芳纶的制备方法

本申请公开了一种共聚改性低缺陷对位芳纶的制备方法，包括以下步骤：在有机溶剂体系中加入摩尔比为1:1的二胺单体和对苯二甲酰氯进行共聚反应，经中和、研磨处理得到改性对位芳纶原液；将所述改性对位芳纶原液通过喷丝及凝固浴成型后，经过水洗、热烘干处理，制得共聚改性低缺陷对位芳纶；所述二胺单体包括对苯二胺和2,2′‑双(三氟甲氧基)‑4,4′‑二氨基联苯，且所述2,2′‑双(三氟甲氧基)‑4,4′‑二氨基联苯在所述二胺单体总摩尔数中的占比为20‑50%。本申请公开的一种共聚改性低缺陷对位芳纶的制备方法，实现了在改善对位芳纶溶解性和可纺性的基础上，同时实现增强油剂与芳纶纤维的结合以及进一步改善二者结合的稳定性的有益效果。
