Bismaleimide-Sulfonamide Homopolymer and Copolymers: Synthesis, Characterization and Microbial Analysis

Abstract

The new bismaleimide monomer N,N'-bis(maleimide)benzenesulfonamide [BMBS], homopolymer N,N'-bis(maleimide)benzenesulfonamide[HBMBS] and copolymers-N,N'-bis(maleimide)benzenesulfonamide-vinyl acetate [CBMBS-A] and N,N'-bis(maleimide)benzene sulfonamide-ethyl vinyl acetate [CBMBS-B] were formed by addition reaction followed by dehydration -cum-cyclization of 4-amino sulfonamide and maleic anhydride. Polymerization process was accompanied by AIBN-THF free radical initiator-solvent selected by trying of many initiatorsolvent system. Melting points were determined by open capillaries method and compounds structures were confirmed from FT-IR spectra (KBr) spectrophotometer. 1 H NMR spectra of all compounds were recorded, using TMS as internal reference. Antifungal activity were examined by various fungus-strain of Candida albicans, Alternaria soloni and Aspergillus niger and results were compared with Griseofulvin as standard reference anti-fungal drug.
