Acrylic copolymers based on Schiff base moiety: Synthesis and their antimicrobial properties

Chlorine containing monomer 4-{[(4-chlorophenyl) imino]methyl}phenyl-2-methacrylate (MSB) was synthesized by reacting 4-[(1E) -2-aza-2-(4-chlorophenyl) vinyl] phenol (SB) with methacryloylchloride. The monomer characteristics was identified by Fourier transform infrared spectroscopy (FT-IR) and 1H-NMR spectroscopy to obtain copolymer composition. Homopolymer and copolymers of MSB with Styrene(ST) at different feed composition was prepared by free radical solution polymerization at 70 ±2°C using 2,2’-azobisisobutyronitrile (AIBN) as an initiator and dimethylformamide (DMF). The copolymer compositions were characterized using 1HNMR data. Fineman-Ross (F-R) and Kelen-Tudos (K-T) methods were used to find reactivity ratio. The molecular weight and polydispersity index of the polymer were obtained using gel permeation chromatography (GPC). Thermogravimetric analysis (TGA) of polymers carried out in a nitrogen atmosphere showed moderate thermal stability. Antimicrobial activity of the polymers was also investigated against various bacteria, fungi and yeast
