Abstract

The current thesis is entitled: ” Synthesis and characterization of some new polymers for water treatment applications” includes three parts First part, Co-polymeric materials of Poly(Ethylene-Co-Vinyl Alcohol) with different ratios, P (EVOH), were chemically modified through a series of reactions including chloroacetylation followed by the amination reaction. The modified copolymers exhibited a satisfying antimicrobial activity towards both Gramnegative bacteria( Pseudomonas aeruginosa, Escherichia coli Klebsiella sp, and Proteus sp) and Gram-positive Staphylococcus aureus ). Besides, some fungi were used such as Aspergillus niger, Candida albican, C. krusi, C. glabrata C. tropicales. The highly observable result was estimated towards the protous species, at a ratio of 27 % Ethylene and 73% Vinyl Alcohol since the inhibition zone reached 41 mm. It was concluded that the antimicrobial activity increased by increasing the percentage of ethyl groups in the copolymeric material.
