In the present work, three esters were prepared by esterification of acrylic acid with alcohols having long different alkyl chain length. The structures of the prepared compounds were confirmed by Infra Red Spectroscopy. Three polymeric compounds were prepared by free radical polymerization of the different acrylate ester with vinyl acetate. All the prepared copolymers were soluble in lube oil. The molecular weights of the prepared compounds were determined by Gel Permeation Chromatography. The prepared copolymers were evaluated as viscosity index improvers and study the rheological properties of lube oil upon addition.
