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 acetyl, amine and sulfide groups were
estimated through the Fourier Transform Infra-Red Spectra (FTIR)
and the Elemental analysis. The antimicrobial activity of the
modified copolymers was tested against various species by the cut
plug procedure. It was concluded that the modified copolymers
exhibited a satisfied antimicrobial activity towards both Gram
positive and Gram negative bacteria. 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. The antimicrobial activity increased by
increasing the percentage of ethyl groups in the copolymeric
material.So, the synthesized polymers were used as biocidal
agents for water treatment.
