dc.description.abstract	4-Vinylpyridine-ethyl acrylate (V/E) copolymers of different compositions have been prepared by free radical bulk polymerization. The copolymer composition has been calculated from ¹H-NMR spectra. The comonomer reactivity ratios of VIE copolymer have been calculated from linear Kelen-Tudos (KT) and non-linear error-in-variables method (EVM). The reactivity ratios obtained from KT and EVM are r_v = 0.34 ± 0.07, r_E = 0.23 ± 0.07 and r_v =0.36 ± 0.08, r_E = 0.25 ± 0.04 respectively. The theoretical triads concentration has been determined from statistical model using terminal model reactivity ratios. The complete spectral assignment of these copolymers has been done with the help of distortion less enhancement by polarization transfer (DEPT) and two dimensional heteronuclear single quantum coherence (HSQC) spectra. The various type of ¹H-¹H couplings in copolymer have been assigned with the help of 2D- total correlated spectroscopy (TOCSY).	en_US
