Abstract
A corrosion inhibitor composition is provided. The corrosion inhibitor composition includes a polycationic polymeric surfactant. The polycationic polymeric surfactant is a copolymer including polymerized units of cationic heterocyclic monomer units and dicationic heterocyclic comonomer units including a quaternary ammonium group. The cationic heterocyclic monomer units and the dicationic heterocyclic comonomer units are alkyl diallyl ammonium units. The quaternary ammonium group comprises a first C8-C16 alkyl group, a second C4-C8 alkyl group, a third C1-C2 alkyl group, and a fourth C1-C2 alkyl group.
