Homopolymers ofdecyl acrylate, dodecylacrylate and isodecylacrylate and copolymers of each of them with styrene were synthesized and characterized. Intrinsic viscosity and viscometric molecular weight of each of them were determined by using Huggins and Mark - Houwink equation respectively. Viscosity index improver (VII) properties were tested with additive doped base oil in terms of viscosity index (VI) of the base oil additive blends. VI values of the additive doped base oils depend on the nature of mineral base oils used and the type and concentration of VI improvers.
