Abstract

Dopamine hydrochloride was converted to monomer N,N-diallyldopamine hydrochloride [(3,4-(HO)₂C₆H₄CH₂CH₂NH⁺(CH₂CH[dbnd]CH₂)₂ Cl⁻] (I). Polymerization of monomer diallydimethylammonium chloride (II) gave homocyclopolymer III, while its copolymerization with 5–20 mol% I afforded copolymers IV. Likewise, II/SO₂ copolymerization and I/II/SO₂ terpolymerization gave respective alternate copolymer V and terpolymers VI. Copolymer IV (containing 20 mol% dopamine motifs) imparted excellent inhibitions of mild steel corrosion in 1 M HCl as well as synergistic inhibition in the presence of iodide ions in 15% HCl at 60 °C. Increasing mol% of dopamine motifs in IV resulted in increasing corrosion protection and demonstrated better efficiency than monomer II and its homopolymer III. Cationic polyelectrolyte IV has been shown to form polyelectrolyte complex/coacervate with three model anionic polyelectrolytes.
