Synthesis and Characterization of Novel Polyamines Containing Different Substitute Groups Via Chemical Oxidative Polymerization

Abstract

In this study, polymers of substitute aromatic amine compounds were synthesized by chemical oxidative polycondensation in aqueous alkaline medium using NaOCl as oxidant. The structures of synthesized compounds were confirmed by FT‐IR, UV‐Vis and NMR analyses. The characterizations of synthesized compounds were made by fluorescence, TG‐DTA, DSC, scanning electron microscopy (SEM) and Brunauer‐Emmett‐Teller (BET) surface area measurements. In addition, electrochemical and electrical conductivity values of compounds were carried out with cyclic voltammetry (CV) and four points probe technique measurements, respectively. Synthesized polymers viewed structural change, optical, electrochemical and thermal differences.

“…In Figure 2b, FT-IR Spectrum for 4-4'-diamino-2,2'-biphenyl disulphonic acid polymer was examined: peaks of NH 2 group at 3400-3337 cm -1 , bending of NH 2 at 1603 cm -1 , asymmetric stretching of SO 2 at 1472 cm -1 , symmetric stretching of SO 2 at 1177 cm -1 and S=O stretching at 1044 cm -1 were observed. In Figure 2c, the stretching vibe vibrations of imine (CH=N) and OH were seen at 1625 cm -1 and 3440 cm -1 , was a result of the condensation reaction between the dye and 4,4'-diamino-2,2'-biphenyl disulphonic acid polymer [16]. Chemical shifts of 1 H-NMR and 13 C-NMR spectrum of the synthesized compounds are given in Figures 3-5.…”
