Synergistic effect of KI on the corrosion inhibition of a poly(diallylammonium chloride)-based cyclocopolymer containing bis-cationic motifs for mild steel corrosion in 20% formic acid

Abstract

The syntheses of poly(diallylammonium chloride) (3) and its copolymers (8a–c) containing hydrophilic/hydrophobic pendants and their role in mitigating mild steel corrosion in aggressive 20% HCOOH is not frequently discussed in the literature.
