Abstract: The copolymers of glycidyl methacrylate/methyl acrylate (G/M) have been synthesized by solution polymerisation using benzene as solvent and benzoylperoxide as an initiator. The 1H-NMR spectroscopy has been used to determine the copolymer compositions. The comonomer reactivity ratios have been determined by Kelen-Tudos (KT) and non-linear least squares error in variable method (EVM) and are found to be rG = 4.03 ± 0.7, rM = 0.45 ± 0.07 and rG=4.6, rM = 0.49, respectively. The Distortionless Enhancement by Polarization Transfer (DEPT), 13C-1H heteronuclear single quantum coherence (HSQC) and Total Correlation Spectroscopy (TOCSY) have been used for the complete spectral assignment of 13C and 1H-NMR spectra.
