Influence of Polyvinyl Palmitate Copolymer As Viscosity Index Improvers For Lube

Polyvinyl palmitates were synthesized by condensing Polyvinyl alcohol with palmitic acid in different ratios and characterized. Intrinsic viscosity and their Molecular weights were found using Mark-Houwnik equation. Viscosity index of diesel oil doped with the prepared polymers were determined and compared. From the results it was observed that there will be slight increase in the viscosity index of the diesel oil at different ratios of additives. From these results it was confirmed that these additives can be used as viscosity index improvers.
