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—R 1 —SH; and R 1 is a hydrocarbyl. The corrosion inhibitor is also disclosed.

Embodiments of the present disclosure are directed to a method of making a reaction inhibiting polymer having a formula of M—CO—NR. The method may comprise reacting PAA with an organic coupling reagent and at least one alicyclic amine to produce the reaction inhibiting polymer. In accordance with another embodiment of the present disclosure, a method of making an acryloyl monomer having a formula of R a —CO—NR may comprise reacting an acrylic acid with an organic coupling reagent and an alicyclic amine to form the acryloyl monomer. R a may be an alkylene moiety, M may be a poly(acrylic) acid backbone. NR may be an alicyclic amine moiety coupled to the polymer backbone or coupled to the alkylene moiety.
