摘要

以咪唑类离子液体为溶剂、亚磷酸三苯酯（TPP）为活化剂合成了聚对苯二甲酰己二胺(PA6T)，考察了反应时间、反应温度、TPP用量和单体浓度对分子量的影响，得到特性黏数［η］为0.49～1.68 dL/g的聚合物.与以水为介质在高压釜中（温度220℃、压力1.8 MPa、反应5 h）合成的预聚物（prePA6T）及再固相缩聚8 h的产物（PA6T-SSP-8 h）相比，离子液体中容易获得特性黏数［η］高的聚合物（PA6T-IL）、聚合时间明显缩短且反应温度降低.

Abstract

Polycondensation of nylon salt of hexamethylerediamine and terephthalic acid was performed in imidazolium ionic liquids (ILs) as solvent and triphenyl phosphate (TPP) as activating agent.The influence of reaction parameters

including the reaction time

the reaction temperature

the concentration of 6T salts and the amount of TPP on molecular weights of the resultantpolymers was investigated.The intrinsic viscosities of PA6T are ranging from 0.49 dL/g to 1.68 dL/g.Otherwise

two other methods were used for the preparation of polyamide from the same monomers to compare the efficiency of polymerization in IL.The polymers obtained were characterized by means of Fourier transform infrared spectroscopy (FTIR)

hydrogen nuclear magnetic resonance (1H-NMR) and gel permeation chromatography (GPC).The molecular weight of PA6T obtained in IL is improved and the distribution of molecular weight is narrow compared with prePA6T synthesized in highpressure autoclave with water as solvent and the products of subsequent solidstate polycondensation for 8 h

and the reaction time was obviously shortened.The thermal properties of PA6Ts were studied by means of TGA

and the thermal stabilities of PA6T polymerized in IL was better than those of prePA6T.
