How Polymers Behave as Viscosity Index Improvers in Lubricating Oils

Advances in Chemical Engineering and Science, 2015
One of the requirements of engine lubricating oil is that it must have a low enough viscosity at low temperatures to assist in cold starting and a high enough viscosity at high temperatures to maintain its load-bearing characteristics. Viscosity Index (VI) is one approach used widely in the lubricating field to assess the variation of viscosity with ...
