    • Disclosed are wholly aromatic polyamide filament and a method of manufacturing the same, characterized in that, in a process of preparing wholly aromatic polyamide polymer, a multiple tubular feed pipe for polymeric monomer and polymerization solvent with specific construction of adjacent inner paths 11a and outer paths 11b which are alternately arranged one another is used to feed either aromatic diacid chloride A or aromatic diamine dissolved in the polymerization solvent B into a polymerization reactor 20 through corresponding one among the inner and outer paths 11a and 11b. The present invention is effective to progress uniform and homogeneous polymerization over all of area of a polymerization reactor 20 leading to reduction of deviation in degree of polymerization, since polymeric monomers are miscible and react together very well immediately after putting the monomers into the reactor 20. Accordingly, the wholly aromatic polyamide filament produced exhibits narrow PDI and increased ACS, so as to considerably improve strength and modulus thereof.
    • 公开了全芳族聚酰胺长丝及其制造方法,其特征在于,在制备全芳族聚酰胺聚合物的方法中,用于聚合单体的多管式进料管和具有相邻内部通道11a和外部通道的特定结构的聚合溶剂 11b彼此交替排列,用于将溶解在聚合溶剂B中的芳香族二酰氯A或芳香族二胺通过内部通路11a和内部通路11b中的相应一个进入聚合反应器20。 本发明有效地在聚合反应器20的所有区域上进行均匀均匀的聚合,导致聚合度偏差的降低,因为聚合单体是可混溶的,并且在将单体放入反应器20后立即非常好地反应。 因此,所生产的全芳族聚酰胺长丝表现出窄的PDI和增加的ACS,从而显着提高其强度和模量。
