Abstract

Six new aromatic Co-polyamides CoP1-CoP6 were prepared by direct Yamazaki's polycondensation reaction of various aliphatic and aromatic dicarboxylic acid (adipic acid, phthalic acid, terephthalic acid and 4-phenylenediacrylic acid) with new various types of aromatic diamine monomers: monomers containing flexible linkages (methylene group), Schiff-base diamine monomer and diamine monomer containing pyridine heterocyclic group and bearing bulky aromatic pendant groups in the 4-position of the pyridine ring, in the presence of LiCl in pyridine and triphenyl phosphite as condensing agents in N-methyl-2-pyrrolidinone as solvent. 4-Phenylenediacrylic acid (PPDAA) was prepared by the condensation reaction of terephthalaldehyde with malonic acid in the presence of pyridine. The monomers were characterized by FTIR and 1H NMR. The resulting polyamides were characterized by FTIR and 1H NMR and their physical properties including solubility, thermal stability and thermal behaviour were studied as well. All of these new polymers show good solubility in polar aprotic solvents and very good thermal stability.
