چکیده
The authors conducted free radical polymerization using an initiator to synthesize a copolymer of isobornyl methacrylate—Acrylonitrile (I/A). reactivity ratios I (r1) and A (r2) monomers were determined as r1 = 1.63 ± 0.14, r2 0.61 0.06 for linear KT (Kelen–Tudos) method 1.58, 0.60 the EVM (Error-in-Variable Method). We interpreted 1H 13C{1H} NMR spectra I/A copolymers DEPT-135 2D HSQC spectra. α-CH3 carbon in I-unit was identified confirmed spectrum, up level triad compositional configurational sequences. CH (C14) β-CH2 peaks also higher, respectively. TOCSY spectrum revealed geminal vicinal interactions within various protons. HMBC provided complete assignment coupling between nitrile, carbonyl, quaternary carbons with CH3 CH2

Characterisation of glycidylmethacrylate/methacrylonitrile copolymers by NMR spectroscopy
Glycidylmethacrylate/methacrylonitrile (G/M) copolymers of different compositions were prepared and a copolymer composition was obtained from quantitative C NMR spectroscopy. Reactivity ratios for comonomers were calculated using the Kelen-Tudos (KT) and non linear error in variable (EVM) methods. The reactivity ratios obtained from KT and EVM are TQ = 1.14 ± 0.1, rM = 0.76 ± 0.06 and rG = 1.12...
متن کاملConfigurational characteristics of ethylene- vinyl chloride copolymers
Rotational isomeric state theory has been used to calculate mean-square unperturbed dimensions (r2>0 and dipole moments (/~> of ethylene-vinyl chloride copolymers as a function of chemical composition, chemical sequence distribution, and stereochemical composition of the vinyl chloride sequences. As was previously found for several other copolymeric chains, (/z2> is much more sensitive to chemi...
متن کاملThermal and dielectrical studies of acryolonitrile with isobornyl acrylate and methacrylate copolymers
Copolymers of Acrylonitrile with Isobornyl acrylate (IBA) and Isobornyl Methacrylate (IBM) were synthesized by free radical polymerization using AIBN as initiator in dimethyl formamide (DMF) at 60 ± 1°C. Thermo gravimetric analysis of the copolymers was performed and their thermal stabilities were studied. Thermal stability of IBM copolymers is found to be more than that of IBA copolymers. The ...
