titleOfInvention | Hyperbranched polymers with active groups as efficient corrosion inhibitors |
abstract | In accordance with one or more embodiments of the present disclosure, a process for preventing corrosion of a metallic surface of a pipeline includes contacting the metallic surface with a corrosion inhibitor. The corrosion inhibitor comprises a polymer of formula R—O—(POL)-Z. R is a straight or branched alkyl or aryl; POL is a polyglycerol based polymer; Z is a non-ionic amine, a cyclic amine having 5 to 8 atoms, a diamine, a triamine, a tetra-amine, a polymeric amine, a thiol, a disulfide, or —NH—R1—SH; and R1 is a hydrocarbyl. The corrosion inhibitor is also disclosed. |
