Abstract (en)
[origin: WO2007035099A1] The invention provides a process of improving the corrosion resistance of metal surfaces by treating the metal surfaces with an aqueous solution of a modified polysaccharide containing from 0.1 to 0.9 anionic groups per monosaccharide unit and from 0.1 to 2.0 C<SUB>1</SUB>-C<SUB>6</SUB> alkyl or alkanoyl groups per monosaccharide unit. The modified polysaccharide has a relatively high molecular weight of between 30 kDa and lO MDa.
