摘要

Abstract

Three diamine monomers with different derivatives of imidazole heterocyclic ring and meta-linked aryl ethers were synthesized and used in polycodensation reaction with various commercial dianhydrides for preparation of a series of novel poly(ether-imide) (PEI)s. The polycodensation reactions were carried out by using conventional method and in a green medium of ionic liquid (IL) without using NMP-pyridine-acetic anhydride. The PEIs were obtained in good yields (80%−96%) with moderate viscosity (0.48−0.66 dL/g) in a shorter reaction time (10 h) in IL as compared with the conventional method (36 h). All of the polymers were amorphous in nature

showed excellent solubility in amide-type polar aprotic solvents with ability to form tough and flexible films

and excellent thermal stability with

s in the range of 212−340℃ and 10% weight loss temperature (T10) up to 570℃ in N2 and 528℃ in air.
