Copolymerization of N-Cyclohexylacrylamide with 9-Vinylcarbazole
A series of copolymers of N-Cyclohexylacrylamide and 9-vinyl carbazole were prepared by free radical polymerization in methanol at 60°C using BPO as initiator. The copolymers composition were characterized by 1H-NMR and 13C-NMR spectroscopy. The copolymer compositions were determined by 1H-NMR analysis and the reactivity ratios of the monomers were determined by Fineman-Ross and Kelen-Tudos methods. The reactivity ratios indicate the formation of random copolymers. Mean Sequence lengths of copolymers are estimated from r1 and r2 values. It shows that the NCA unit increases in a linear fashion in the polymer chain as the concentration of NCA in the monomer feed. Antimicrobial activity of NCA copolymers showed that the copolymers exhibit more activity than the control for the both bacteria and fungi.
