High Temperature and Organosoluble Poly(amide-imide)s Based on 1,4-Bis[4-aminophenoxy]butane and Aromatic Diacids by Direct Polycondensation: Synthesis and Properties
A series of high temperature and organosoluble poly(amide-imide)s 8a–g were prepared by direct polycondensation from 1,4-bis[4-aminophenoxy]butane 4 and various aromatic diacids 7a–g in a medium consisting of N-methyl-2-pyrrolidone (NMP)/triphenyl phosphite (TPP)/calcium chloride (CaCl2)/pyridine sy...

| Summary: | A series of high temperature and organosoluble poly(amide-imide)s 8a–g were prepared by direct polycondensation from 1,4-bis[4-aminophenoxy]butane 4 and various aromatic diacids 7a–g in a medium consisting of N-methyl-2-pyrrolidone (NMP)/triphenyl phosphite (TPP)/calcium chloride (CaCl2)/pyridine system. Aromatic diacids 7a–g were synthesized by reaction of 3,3′,4,4′-benzophenone tetra carboxylic dianhydride 5 and various amino acids 6a–g. All of the above polymers were fully characterized by 1H-NMR and FT-IR spectroscopy, inherent viscosity, solubility test and thermogravimetric analysis (TGA). The resulted polyamides (PAs) 8a–g have showed admirable good inherent viscosities, thermal stability and solubility. |
