7-Acryloyloxy-4-methylcoumarin (ACU) monomer was polymerized with N-cyclohexyl-acrylamide (NCA) in different feed ratio using AIBN (Azobisisobutyronitrile) as initiator in DMF. 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 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.
