“…The 18.7 ppm is attributed to the methyl carbon of O-CH 2 -CH 3 and the methylenoxy carbon of PGMA and EMA gave a signal at 65.8 and 60.9 ppm, respectively [22,23]. The peaks at 48.8 and δ 44.7 ppm correspond to the methyl and methylene carbon of the epoxy group, respectively [20,21].…”

The ionic conductivity of poly(glycidyl methacrylate-co-ethyl methacrylate) [P(GMA-co-EMA)]-lithium perchlorate (LiClO 4 )-ethylene carbonate (EC) electrolyte and photovoltaic performances of dye-sensitized solar cells (DSSC) utilizing the electrolyte were investigated. P(GMA-co-EMA) as a host material of the electrolyte was synthesized by UV-curing and characterized by nuclear magnetic resonance (NMR). P(GMA-co-EMA) based solid polymer electrolyte containing 80 wt% EC exhibited the highest room temperature ionic conductivity. The crystallinity degree of the electrolyte decreases with the EC content, as confirmed by X-ray diffraction (XRD) studies. The electrochemical stability investigated by cyclic voltammetry (CV) reveals that the electrolyte is stable up to 4.8 V. A dye-sensitized solar cell of fluorine tin oxide (FTO)/TiO 2 -dye/P(GMA-co-EMA)-LiClO 4 -EC/Pt possessed the photovoltaic effect with a short-circuit current density (J sc ) of 4.85 × 10 -3 mA cm -2 and open circuit voltage (V oc ) of 0.4 V, respectively, under light intensity of 100 mW cm -2 .

“…The co-polymers of glycidyl methacrylate and styrene have been reported by Dhal [8]. Vijayanand et al [9] reported the synthesis and characterization of 3,5-dimethyl phenyl methacrylate co-polymers with GMA. Synthesis and characterization of activated acrylates based on the co-polymers of 4-acetamidophenyl acrylate with GMA have been reported recently [10].…”

Co-polymers of N-phenyl methacrylamide and glycidyl methacrylate of different compositions were synthesized by free radical solution co-polymerization of the monomers in dimethylformamide using benzoyl peroxide as the initiator at 70 • C. Solubility of the co-polymers was tested in various solvents. The molecular structure of the co-polymers was elucidated by infrared and proton nuclear magnetic resonance spectroscopy. The composition of the co-polymers was determined from their 1 H-NMR spectra by using the intensities of aliphatic and aromatic protons present in the co-polymer. The Finemann-Ross and Kelen-Tüdos models have been employed to determine the reactivity ratios of the monomers. The intrinsic viscosities of the co-polymers of GMA and PMA were determined using a Ubblehode viscometer. The thermal transitions of the co-polymers were determined using differential scanning calorimetry and thermogravimetric analysis.

“…It shows peaks at 3115 and 3080 cm 21 corresponding to the C-H stretching of the aromatic system. The symmetrical and asymmetrical stretching due to the methyl and methylene groups are observed at 2996 and 2950 cm 21 . The peaks at 1750 and 1735 cm 21 are attributed to the ester carbonyl stretching of NMPM and MMA units.…”

“…The calculation of monomer reactivity ratios requires the mathematical treatment of experimental data based on the composition of the copolymers related to the initial feed. 1 H-NMR spectroscopy analysis has been established as a powerful tool for the determination of tacticity, sequence distribution and estimation of copolymer composition, due to its simplicity, rapidity and sensitivity (19)(20)(21)(22)(23). The presence of aromatic side substituents, instead of aliphatic residues in polyacrylic chains, gives rise to noticeable effects on the splitting of the NMR signals of several acrylic systems.…”

A new methacrylic monomer, 4-nitro-3-methylphenyl methacrylate (NMPM) was prepared by reacting 4-nitro-3-methyl phenol dissolved in methyl ethyl ketone (MEK) in the presence of triethylamine as a catalyst. Copolymerization of NMPM with methyl methacrylate (MMA) has been carried out in methyl ethyl ketone (MEK) by free radical solution polymerization at 70 + 18C utilizing benzoyl peroxide (BPO) as initiator. Poly (NMPM-co-MMA) copolymers were characterized by FT-IR, 1 H-NMR and 13 C-NMR spectroscopy. The molecular weights (M w and M n ) and polydispersity indices (M w /M n ) of the polymers were determined using a gel permeation chromatograph. The glass transition temperatures (T g ) of the copolymers were determined by a differential scanning calorimeter, showing that T g increases with MMA content in the copolymer. Thermogravimetric analysis of the polymers, performed under nitrogen, shows that the stability of the copolymer increases with an increase in NMPM content. The solubility of the polymers was tested in various polar and non-polar solvents. Copolymer compositions were determined by 1 H-NMR spectroscopy by comparing the integral peak heights of well separated aromatic and aliphatic proton peaks. The monomer reactivity ratios were determined by the Fineman-Ross (r 1 ¼7.090:r 2 ¼ 0.854), Kelen-Tudos (r 1 ¼ 7.693: r 2 ¼ 0.852) and extended Kelen-Tudos methods (r 1 ¼ 7.550: r 2 ¼ 0.856).
