Abstract
Functional monomer, N-phenyl methacrylamide (PMA) was synthesized by reacting methacryloyl chloride with
aniline and its copolymers with acrylonitrile (AN) in various feed ratios were synthesized using free radical
initiator (benzoyl peroxide) in N,N-dimethylformamide at 70°C. Copolymer structure was elucidated by infrared
and proton nuclear magnetic resonance spectroscopy. The copolymer composition was determined from the
corresponding 1H NMR spectra of the copolymers. The relative reactivity of PMA and AN were determined
by Finemann–Ross and Kelen–Tudos methods. Intrinsic viscosity was calculated for all the copolymers in
dimethylformamide. Thermal characterization of the copolymers was carried using thermo gravimetric analysis.
Activation energy for degradation of the copolymers was determined by Briado and Horowitz’s methods.
