Synthesis, Characterization and Anti Microbial Studies of Copoly (N Vinylpyrrolidone – Maleic Anhydride) with N, NDiethylaminoethanol

A copolymer of N-vinylpyrrolidone (NVP) and Maleic anhydride (MA) is synthesized by free radical copolymerization with 2,2-Azo-bisisobutyronitrile(AIBN) as initiator at 650C in dioxane solution, under nitrogen atmosphere. The copolymer obtained is characterized by FTIR and NMR. The copolymer is grafted with N,N- Diethylaminoethanol (DEAE) in two different ratios. The antimicrobial property of these compounds is investigated by agar well diffusion method. Two gram +ve bacterial strains used are Bacillus pumillus – 1640 and Staphylococcus aureus – 3160, the gram –ve bacterial strain used is Escherichia coli – 45 . The fungal strains used are Fusarium oxysporum – 2087 and Aspergillusniger – 4325. Keywords - Antimicrobial activity, Copolymerization, Maleic anhydride, N-vinylpyrrolidone,
