Abstract
The objective of this work is to study the effect of polymeric additives upon the viscosity of two different base stocks over the temperature range -25°C to 10°C. The two base stocks being, (i) Imperial oil's MXT-5 base stock, and (ii) Chevron oil's Group III base stock. Four different viscosity-index improvers at five concentrations were employed. The viscosity-index improvers' behavior was studied in presence of pour-point depressants. The viscosity-index improvers being: hydrogenated diene copolymer (HDP) [C95-209], dispersant olefin copolymer (DOCP) [C96-309], olefin copolymer (OCP) [C98-129], polymethylacrylate (PMA) [C93-009]. The pour-point depressants are: acryloid 154-70 and paraflow 387. Kinematic viscosities and densities of all the base stocks and dilute polymer oil solutions were measured at -25, -20, -15, -10, -5, 0.0, and 10°C. Relative and specific viscosity values for the lubricant/polymer systems were calculated and are reported at the temperature levels employed in this study.Dept. of Civil and Environmental Engineering.
