摘要

采用低温溶液缩聚的方法，在

-甲基吡咯烷酮(NMP)-氯化锂(LiC1)溶剂体系中引入了 4，4’-二氨基二苯醚(4，4’-ODA)作为第三单体，与邻氯对苯二胺和对苯二甲酰氯(TPC)反应，得到可用于直接湿纺的共聚物纺丝溶液。将原液进行湿法纺丝，经水洗干燥后得到原丝，采用SEM和电子拉伸试验机表征纤维的结构与力学性能。研究结果表明，共缩聚后可以得到粘度高、分子量大、稳定性好的纺丝原液，通过湿法纺丝制得的纤维具有良好的取向度、结晶度和热性能。

Abstract

Copolymer solution which can be spun directly was prepared by low-temperature solution polycondensation using 2-chloro-p-phenylenediamine

terephthaloyl chloride (TPC) and 4

4'-diaminodiphenyl ether (4

4'-ODA) in the solvent system of N-Methyl pyrrolidone/Lithium Chloride (NMP/LiCl). Precursor fibers were obtained by wet-spinning followed by washing and drying

and then the structure and mechanical property of the fibers were characterized by SEM and electronical tensile testing machine. The results indicated that spinning solution with high viscosity

high molecular weight and good stability can be obtained by copolycondensation. Furthermore

the fibers prepared by wet spinning possess high degree of orientation

high crystallization and good thermal performance.
