“…[4][5][6][7][8] Copolyamides from 2, 6-naphthalene diacid with a mixture of two aromatic diamines containing ether linkage and meta-catenation moiety produced aramids which were soluble in solvents namely NMP and DMSO. Solubility of aromatic polyamides was enhanced by introducing cardo [9][10][11][12][13] and bulky pendant units [14][15][16][17][18][19] such as dibenzobarrelene/ crown ethers and acyclic ethylene oxide in the polyamide backbone. Pendant bulky groups promote chain separation and improve processability.…”

A new aromatic diacid, containing preformed diamide functional group, C8 alkylene moiety, and two methylene spacers, viz; N, N′‐bis(4′‐carboxy methylene phenyl) decane diamide (BCPDD) was designed and successfully synthesized. The structure of BCPDD was confirmed by FT‐IR, NMR (1H, 13C) spectroscopy and mass spectrometry. The corresponding series of new polyamides were prepared via reactions of diacid (BCPDD) and commercial aromatic diamines by Yamazaki's phosphorylative direct polycondensation method. Physical properties of these polyamides such as inherent viscosity, solubility in organic solvents, glass transition temperatures by DSC, thermal stability by TGA, and amorphous‐crystalline mature by XRD were studied. The incorporation of preformed amide, methylene spacers, and C8 alkylene moiety greatly affected polyamide properties such as solubility in common organic polar solvents, glass transition temperature, and thermal stability. These polyamides were mostly amorphous in nature and dissolved in polar aprotic solvents such as N‐methyl‐2‐pyrrolidone, N, N‐dimethylacetamide, N, N‐dimethylformamide, dimethyl sulfoxide, m‐cresol, and pyridine. Inherent viscosities of these polyamides were in the range of 0.40–0.67dL/g; indicating the formation of moderate to high molecular weights. These polyamides exhibited good thermal stability having temperatures for 10% weight loss (T10) in the range of 404–578°C and the char yields at 800°C in the range of 35–65%. The glass transition temperatures; as determined by DSC were in the range of 204–235°C.

A new polyimine polymer (PL) containing sulphone functional groups was prepared from polycondensation of Schiff base (L) with terephthaloyl chloride at a very moderate condition. The polymer metal complexes were then synthesized from the reaction of polymer with metal salts. Scanning electron microscope (SEM), Fourier‐transform infrared spectroscopy (FTIR), X‐ray diffraction analysis (XRD), thermal gravimetric analysis (TGA), derivative thermogravimetry (DTG), proton nuclear magnetic resonance (1H NMR), and CHNS elemental analysis have been used to characterize all the synthesized materials. The excellent thermal stability of PL was specified by TGA. The optical features were assessed with the UV‐visible technique. The polymer complexes represent absorbance at the same wavelength as L and PL. The synthesized polymer metal complexes have a band gap varying from 3.19 (CuPL) to 2.77 (CdPL) eV. The inherent viscosities for the synthesized polymer is 0.4490 dL/g in DMF at 25 °C, indicating their moderate molecular weight.
