Synthesis, Characterization and Anti Microbial Studies of Copoly (N-Vinylpyrrolidone � Maleic Anhydride) With N, N-Diethylaminoethanol

Abstract
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
