The two copolymer systems of styrene bearing diethanol amine side group and styrene were prepared by free radical polymerization method at 60 ∘ C in presence of 1,4-dioxane as solvent and AIBN as initiator. Their metal complexes were prepared by reaction of the copolymer used as ligand P(DEAMSt-co-St)L and Ni(II) and Co(II) metal ions, which was carried out in presence of ethanol and NaOH at 65 ∘ C for 48 h in pH = 7.5. The structures of the copolymers used as ligand and metal complexes were identified by FT-IR, 1 H-NMR spectra, and elemental analysis. The properties of the copolymers used as ligand and metal complexes were characterized by SEM-EDX, AAS, DSC, TGA, and DTA techniques. Then, the electrical properties of the copolymers and metal complexes were examined as a function of the temperature and frequency, and the activation energies ( ) were estimated with conductivity measurements.

“…The dielectric constant was decreased with increasing frequency. This trend in dielectric constant has been reported in many studies observed at frequency ranges of a few MHz [33,34]. A somewhat more rapid decrease in e 0 can be seen over the frequency range 1-300 kHz.…”

2-Hydroxy-3-(1-naphthyloxy)propyl methacrylate (NOPMA) monomer was synthesized from reaction of 2-[(2-naphthyloxy)methyl]oxirane with methacrylic acid in the presence of pyridine. The polymerization of NOPMA was carried out by free radical polymerization method in the presence of AIBN at 60°C. The structure of monomer and polymer was characterized by 1 H-NMR, 13 C-NMR and FT-IR spectroscopy techniques. The glass transition temperature and averagemolecular weights of poly(NOPMA) were measured using differential scanning calorimetry and gel permeation chromatography, respectively. The thermal degradation behavior of poly(NOPMA) has been investigated by FT-IR studies of the partially degraded polymer and thermogravimetry. The cold ring fractions (CRFs) were collected at two different temperatures, initially fraction-1 (CRF 1 ) is from room temperature to 320°C, and the other fraction-2 (CRF 2 ) is from 320 to 500°C. The volatile products of the degradation were trapped at -195°C (in liquid nitrogen). All the fractions were characterized by FT-IR, 1 H and 13 C-NMR spectroscopic techniques, and the cold ring fractions (CRFs) were also characterized by GC-MS. For the degradation of polymer, the major compound between products of CRFs is a-naphthol. The GC-MS, FT-IR and NMR data showed that depolymerization corresponding to monomer was not prominent below 320°C in the thermal degradation of poly(NOPMA). The mode of thermal degradation containing formation of the major products was identified. The dielectric permittivity (e 0 ), the loss factor (e 00 ) and conductivity (r ac ) were measured using a dielectric analyzer in the frequency range of 50 Hz to 20 kHz.

“…The band at 1735 cm À1 (C@O stretching vibration) in the spectrum of PVC-DEAB, which is an important evidence of the acylation, is characteristic of the a-bromocarbonyl group, BrAC(CH 3 ) 2 C@O [20]. Two methyl groups attached to the same carbon atom also exhibit two distinctive absorption bands as a shoulder at 1390 and 1370 cm À1 .…”
