摘要
研究了加入一系列第3单体改性聚对苯二甲酰对苯二胺后,在不同的缩聚工艺下对助剂的加入量、单体配比、聚合溶液浓度以及反应时间进行了考察,确定了制备高分子量改性聚对苯二甲酰对苯二胺树脂的最佳工艺条件。聚合物溶液经直接纺丝得到初步拉伸丝。
The effects of solution concentration, monomer ratio and reaction time were studied in detail after introducing a series of the third monomers into the condensation polymerization system, aimed at modifying poly(p -phenyleneterephthalamide) . The fiber was prepared by spinning directly from the polymer solution.
