<p>POLYAMIDE CORROSION INHIBITOR Oil dispersible ferrous metal corrosion inhibitors are prepared by first forming a primary amine-terminated amide adduct by reacting a mixture of monomeric, dimeric and trimeric 1,6-hexanediamine with polyfunctional acids at a ratio of reactants such that the adduct is substantially completely terminated with primary amine groups and neutralizing the primary amine-terminated amide adduct with a carboxylic acid. Alternatively, water dispersible adducts may be prepared by reacting the primary amine-terminated amide adduct with an oxirane compound to produce a polyether derivative of the amineterminated adduct. 1.</p> |
