摘要

New organo-soluble poly(amide-imide)s (PAIs) 8a-8f were prepared from newly synthesized 1

2-bis[4

4’-(trimellitimido)phenoxy]ethane 6 via direct polycondensation with various aromatic diamines. The diacid 6 was synthesized by the condensation reaction of 1

2-bis[4-aminophenoxy]ethane 4 with trimellitic anhydride 5 in acetic acid. All polymers were obtained in quantitative high yields with inherent viscosities of 0.48-0.61 dL/g. All of these polymers were highly soluble in organic solvents such as

N-methyl-2-pyrrolidone (NMP)

dimethylformamide (DMF)

N’-dimethylacetamide (DMAc) and dimethylsulfoxide (DMSO) at room temperature and were fully characterized by means of NMR spectroscopy

FTIR spectroscopy

elemental analyses

inherent viscosity

solubility test

specific rotation

differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
