“…A series of polyacrylamide and dithiocarbamade metal polymers complexes with divalent Cu, Ni, Zn, Co and Hg metal ion have been prepared, thermal studies have been reported [10]. Moreover, Cross-linked polyacrylamide-Cu(II) complexes with divinylbenzene have been explored for their catalytic activity [10,11]. The thermal studies of polymer complexes derived from chelation between divalent Co, Ni, Cu and Cd metal ions and poly(ethylene glycol) ligand have been investigated [12].…”

Eight polymer-metal complexes were synthesized from complexation of divalent Mn(II), Ni(II), Co(II), and Cu(II) metal ions with modified polystyrene-alt-(maleic anhydride) (PSMAP and PSMAM) ligands. The structures of these new complexes were characterized using a variety of techniques, including magnetic moment susceptibility, conductance measurements, FT-IR spectroscopy, ultraviolet-visible (UV-VIS), thermogravimetric analysis (TGA), as well as scanning electron microscopy (SEM). All metal-polymer complexes have a non-electrolytic nature based on conductance measurements. The polymer molecule behaves as neutral bidentate NO ligand through O atoms of carbonyl (C=O) and N atoms of amide (O=C-NH). Divalent Mn2+, Ni2+, Co2+ and Cu2+ complexes have an octahedral geometry based on their electronic spectra and magnetic values. Based on thermal analysis data, those new complexes are more thermally stable than the ligands. SEM and TEM are manipulated to give the surface structure and the particle size measurements where they give different shapes and sizes of the synthesized complexes.

“…Polyacrylamide (PAM) is a water‐soluble polymer with wide applications in many fields such as infiltrative film [35], biosensor [36], anlistatig coat [37], nonlinear optical devices [38], and the flocculation of municipal and industrial waste [39]. On the other hand, it is attractive in fundamental research such as catalysis [40], polyelectrolytes [41], and biomedical fields [42]. Hybrids of PAM and inorganic compounds such as clay [43], graphite oxide [44], α‐zirconium phosphate [45], metal (Au, Pd) [46], and PbS [47] have been investigated.…”

Polyacrylamide‐calcium carbonate (PAM/CaCO3) and polyacrylamide‐calcium sulfate (PAM/CaSO4) nanocomposites were prepared via solution‐mixing technique. The resulting PAM‐based nanocomposites with various CaCO3 and CaSO4 nanoparticles contents (0–4% w/w) were investigated. Nanoparticles of CaCO3 and CaSO4 were synthesized by in situ deposition technique. In this technique, the surface modification of nanoparticles was performed by nonionic polymeric surfactant. The particle size of nanoparticles was recognized by X‐ray diffraction and scanning electron microscope (SEM) analysis which confirms that the particle has diameter of 25–33 nm. As prepared, nanocomposites films (thickness, 40‐μm) were characterized by Fourier transform infrared (FT‐IR), SEM, and energy‐dispersive X‐ray spectroscopy (EDS). FT‐IR shows the chemical structure of nanocomposites where as SEM analysis suggested that the nanofillers dispersed well in polymer matrix and EDS shows the elemental composition of the nanocomposite samples. Thermal properties of the nanocomposites were studied by using differential scanning calorimetric analysis. The PAM/CaCO3 and PAM/CaSO4 nanocomposites showed a higher glass transition temperature and a better thermal stability compared to the pure PAM. The glass transition temperature (Tg) of nanocomposites increases with increase in content of nanoparticles. It may be owing to the interaction between inorganic and organic components. POLYM.

The free radical copolymerization of 4‐(1‐methyl‐1‐mesityl‐3‐cyclobutyl)‐2‐N‐1, 3‐thiazole‐2‐yl methacrylamide (MCTMA) with 2‐[(5‐methylisoxazol‐3‐yl)amino]‐2‐oxo‐ethyl methacrylate (IAOEMA) has been carried out in 1, 4‐dioxane at 65 °C ± 1 and were analyzed by Fourier transform infrared, 1H NMR, 13C NMR, and gel permeation chromatography. 1H‐NMR analysis was used to determine the molar fractions of MCTMA and IAOEMA in the copolymers. The monomer‐reactivity ratios were calculated according to the general copolymerization equation using Kelen–Tüdõs and Finemann–Ross linearization methods. The reactivity ratios indicated a tendency toward random copolymerization. The polydispersity indices of the polymers, determined with gel permeation chromatography, suggested a strong tendency for chain termination by disproportionation. The thermal behaviors of copolymers with various compositions were investigated by differential scanning calorimetry and thermogravimetric analysis. The glass‐transition temperature of the copolymers increased with increasing MCTMA content in the copolymers. Also, the apparent thermal decomposition activation energies were calculated by the Ozawa method with a Shimadzu TGA 60 thermogravimetric analysis thermobalance. All the products showed moderate activity against different strains of bacteria and fungi. © 2007 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 46: 530–542, 2008
