摘要: A series organosoluble and heterocyclic poly(ether-amide)s (PEA)s were synthesized from a new diamine containing pyridine moiety four aliphatic-aromatic dicarboxylic acids by direct polycondensation reactions. Dicarboxilic 4a–4d ether groups in two step At first, dialdehydes 3a–3d dibromo alkanes 1a–1d 4-hydroxybenzaldehyde 2, then dicarboxilic malonic acid solvent free reaction. On the other hand, 8 ring was The structures of monomers polymers proven FTIR, NMR spectroscopy elemental analysis. Also all above fully characterized inherent viscosity, solubility tests, gel permeation chromatography (GPC), differential scanning calorimetry (DSC) thermogravimetric analysis (TGA). resulted PEAs have shown good viscosities, thermal properties.
