ABSTRACT
Copolymerization of N-tert-butylacrylamide (NTB) and 7-acryloyloxy-4-methyl coumarin (AMC) was carried out in DMF medium at 60°C using AIBN as initiator. The copolymers were characterized by ¹H-NMR spectroscopy and the copolymer compositions were determined by ¹H-NMR analysis. The reactivity ratios of monomers were determined by Fineman -Ross and Keleln-Tudos methods. The reactivity ratios were found to be r1= 1.15 and r2 = 0.70 by Fineman -Ross and r1 = 1.16 and r2 = 0.72 by Kelen-Tudos . These values suggest that NTB is more reactive than AMC. The r1.r2 = 0.805 value indicates the formation of random copolymers. Antimicrobial activities of different copolymers synthesized were also studied against different bacteria and fungi.
