polymer - Schlumberger Oilfield Glossary

Polymers may be classified by their structure and may be linear, branched or less commonly cyclic. Copolymers contain two or more different monomers that can be arranged randomly or in blocks. In solution, entangled polymer chains can create networks, giving complex viscosity behavior. Polymers that ionize in solution are called polyelectrolytes.

A Simple Explanation of Viscosity Index Improvers

Viscosity index, noun An arbitrary scale for lubricating oils that indicates the extent of variation in viscosity with variation of temperature. Improver, noun A person or thing that improves. V iscosity index (VI) is a commonly used method of measuring a fluid's change of viscosity in relation to temperature. The higher the VI, the smaller the

Viscosity index improvers are used to limit the rate of change of viscosity with temperature. These improvers have little effect on viscosity to low temperature. However, as the oil heated the improvers enable the oil viscosity to increase within the limited range permitted by the type and concentration of the additive.

Understanding Viscosity Index Improvers

Remember, viscosity is a fluid's measure of resistance to flow and shear. The viscosity index is a measure of a fluid's change in viscosity relative to its change in temperature. Viscosity index improvers resist the thinning that occurs in a lubricant as the temperature is increased.
