摘　　要：无卤阻燃聚酰胺6是对普通聚酰胺6进行改性后得到的一种高分子材料,适用于加工阻燃纤维。文章对无卤阻燃聚酰胺6和普通聚酰胺6两种高聚物的流变行为进行了对比研究,发现相对于后者而言,前者的表观黏度较小,既是切敏材料也是温敏材料。最后提出,无卤阻燃聚酰胺6纤维的加工应当更加严格控制工艺参数。Halogen-free flame-retardant PA6 is a polymer obtained by modifying conventional PA6 and is suitable for processing into flame-retardant fiber.This paper compared the rheological behavior of halogen-free flame-retardant PA6 and conventional PA6,and found that halogen-free flame-retardant PA6 has a lower apparent viscosity than the conventional PA6,and is more sensitive to shearing force and thermo condition than conventional PA6.The authors put forward that during the processing of halogenfree flame-retardant PA6 fiber,its technological parameters should be controlled more strictly.
