N-Alkyl acrylates and n-alkyl methacrylates were prepared by esterification of acrylic and methacrylic acids with two long-chain alcohol blends NAFOL 2022 and NAFOL 1822. The prepared monomers were characterized and polymerized individually. In addition, copolymers of n-alkyl acrylate-n-alkyl methacrylate, and n-alkyl methacrylate-vinyl acetate and a terpolymer of n-alkyl acrylate-acrylic acid-vinyl acetate were also synthesized. These polymers were also characterized and then evaluated as flow improvers in Khalda mixture- and Salam Egyptian waxy crudes. The majority of the prepared additives showed good performance in improving the flow properties of the tested crudes.
