The influence of poly(4-vinylpyridine-poly(3-oxide-ethylene) tosyle) P4VPPEO5000Ts, on the corrosion inhibition of iron in molar sulphuric acid solution is studied using weight-loss, polarisation resistance, potentiodynamic and EIS measurements. P4VPPEO5000Ts is an excellent inhibitor and its inhibition efficiency increases with the increase of concentration to attain 100% since 2.5 × 10−8 M. Potentiodynamic polarisation studies clearly reveal that it acts as a mixed-type inhibitor. The polymer studied reduces the corrosion rates. E% values obtained from weight-loss, corrosion current density, polarisation resistance and EIS methods are in good agreement. Adsorption of this compound on iron surface has an S-shaped adsorption isotherm with two consecutive steps.
