Abstract
The inhibitive nature ol polyvinyl alcohol-anthranilic acid (PVAAA) on the corrosion of mild steel in 1 M IlCl solution under various
conditions has been investigated by means of weight loss, potentiodynamic. polarizalion and AC impedance methodsrThe studies show!
that polyvinyl alcohol-anthranilic acid exhibited excellent inhibition property. The potentiodynamte polarization studies reveal that the
-polyvinyl aleohoTanthranilic,acid acts as a nuxed typcvinhibitOT. The adsoijption of the polymer on the mild steel surface was found to
obey Langmuir andTemkin adsoipUoniiotherms.
