Abstract (en)
[origin: WO9611291A1] Phosphonated cotelomers derived from acrylic acid and 2-acrylamilo-2-methyl propane sulphonic acid have been found to interact synergistically with known phosphonate corrosion inhibitors especially hydroxy ethylidene diphosphonic acid, 2 phosphono butane 1,2,4 tricarboxylic acid and 2-hydroxy phosphono acetic acid. Combinations of these synergistic components can be added to aqueous media to inhibit the corrosion of metal surfaces more efficiently.
