Synthesis, Characterization and Antimicrobial Screening of Coumarin Copolymers

7-Acryloyloxy-4-methylcoumarin (ACU) monomer was polymerized with N-cyclohexylacrylamide (NCA) in different feed ratio using AIBN (Azobisisobutyronitrile) as initiator in DMF. The copolymers were characterized by H NMR spectroscopy and the copolymer compositions were determined by H NMR analysis. The reactivity ratios of monomers were determined using linear methods like Fineman-Ross and Kelen-Tudos. The value showed that ACU is more reactive than NCA. The copolymers contained a higher proportion of ACU units. Mean sequence lengths of copolymers were estimated from r1 and r2 values. ACU unit increases in a linear fashion in the polymer chain as the concentration of ACU increases in the monomer feed. The copolymers were tested for their antimicrobial properties against selected microorganisms.
