POLYMER STRUCTURES: STUDIES ON THERMAL AND MICROBIAL REACTIVITY OF COPOLYMERS AND TERPOLYMERS OF [AZO - N - 4 - BROMOPHENYL] SUBSTITUTED MALEIMIDE CHAIN WITH ACRYLATES VINYLS

We report the synthesis, characterization, thermal and microbial properties of a series of [4 - N - Phenylethanamide azo - 3 - N - (4 - Bromophenyl)Maleimide - co - Acrylonitrile] [C1 - PAMI - B], [4 - N - Phenylethanamide azo - 3 - N - (4 - Bromophenyl)Maleimide - co - Acrylic acid] [C2 - PAMI - B ] , [4 - N - Phenylethanamide azo - 3 - N - (4 - Bromophenyl)Maleimide - co - Vinyl acetate] [C3 - PAMI - B] copolymers and [4 - N - Phenylethanamideazo - 3 - N - (4 - Bromophenyl)Maleimide ? Acrylonitrile - Vinyl acetate] [T1 - PAMI - B] and terpolymer [4 - N - Phenylethanamideazo - 3 - N - (4 - Bromop henyl)Maleimide ? Acrylic acid - Vinyl acetate] [T2 - PAMI - B] terpolymers of maleimide containing compounds. Polymer’s structures of different side groups with same chain back - bone of maleimide are performed for the study of effects on glass transition point along with chain - flexibility. All polymer’s structure are confirmed by C/H/N - elemental analysis, FT - IR and 1HNMR spectral analysis. Molecular weight and polydispersity are determined by gel permeation chromatography (GPC). Thermal stability of polymers ar e investigated from thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Microbial activities of the polymers are also examined on various bacteria / fungi.
