Title:
全芳香族ポリアミドフィラメントの製造方法
Document Type and Number:
Japanese Patent JP4658195
Kind Code:
B2
Abstract:
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 and outer paths 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. 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.
