The new acrylamide monomer, N-(4-Bromophenyl)-2-methacrylamide (BrPMAAm) has been synthesized by reacting 4-Bromoaniline with methacryloyl chloride in the presence of triethylamine(NR3) at 0-5°C. The radical-initiated copolymerization of (BrPMAAm), with 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) has been carried out in dimethylformamide (DMF) solution at 70± 1°C using 2,2'-azobisisobutyronitrile (AIBN) as an initiator with different monomer-to-monomer ratios in the feed. The copolymers were characterized by FTIR, 1H- and 13C-NMR spectroscopy. The copolymer composition was evaluated by nitrogen content (N for AMPS-units) in polymers led to the determination of reactivity ratios. The monomer reactivity ratios for BrPMAAm (M1)-AMPS (M2) pair were computed using the Fineman-Ross (F-R), Kelen-Tüdös (KT) and Extended Kelen-Tüdös (EKT) methods. These parameters were also estimated using a non-linear computational fitting procedure, known as reactivity ratios error in variable model (RREVM). The mean sequence lengths determination indicated that the copolymer was statistically in nature. By TGA and DSC analyses, the thermal properties of the polymers have been studied. The antimicrobial effects of polymers were also tested on various bacteria, and yeast. Copyright © Taylor & Francis Group, LLC.
