“…Further, the absence of C=C band, which usually appears at 1610 cm -1 , proved that the acrylamide monomer has been completely converted to polyacrylamide and no residue of monomer is present in the polymer [16,17]. Ghosh et al studied the FT-IR spectra of polyacrylamide; their finding is in a good agreement with our results [18].…”

Using free radical solution polymerization technique and Mannich reaction, five different polyacrylamides with similar molecular weight but variable charge densities were synthesized. High molecular weight polyacrylamides were synthesized using potassium persulfate and N,N,N',N'-tetramethylethylenediamine system as initiators. This was achieved by increasing the concentration of acrylamide monomer. They were then characterized by infrared spectroscopy, viscosity measurements and glass transition temperature measurement. These compounds with various cationic charge densities from 48.2, 161.7, 355, 425 and 485 C/g were prepared through Mannich reaction. The results indicate, by increasing the acidity of the polyacrylamide solution using sulfuric acid, the pH of the polyacrylamide solution decreases correspondingly. As a result, the positive charges increased resulting in the enrichment of charge densities.

“…A relatively high mass loss zone then follows till about 400ºC which correspond to cyclization of polyacrylamide and associated liberation of NH 3 . A much sharper mass loss zone appears over the temperature zone of 400-500ºC accounting DOI: 10.9790/5736-1004016773 www.iosrjournals.org 73 |Page for large-scale thermal degradation with the liberation of H 2 , CO and NH 3 , leaving a residue of about 22% at 600ºC (9).…”

“…It is continuously reformed day by day through the modulation of doping or by introducing functionality for making it more attractive for technological applications [6][7]. Recently few works have been reported on the chemical modification of carbohydrate polymer with PANI such as a semi-interpenetrating based chitosan/polyaniline and chitosan-polyaniline copolymers studied under different pH conditions [8][9][10][11].…”

A novel electrically active, water soluble gum acacia-polyaniline (GA-PANI) hybrid was synthesized using ceric ammonium nitrate as initiator in acidic medium. The representative hybrid material was characterized using UV-visible, FTIR and SEM taking polyaniline as reference. The composition of aniline to gum acacia was tailored to optimize possible cross-linking in side the hybrid. The hybrid material exhibited pH switching electrical conductivity, which was decreased with increasing pH of the material. I-V characteristics and acid-base sensitivity of the hybrid material were extensively investigated in order to find out its electronic behavior during current flow.
