taken as the extent of interaction of the polymer with the base stock, greater the thickening property; greater is the extent of interaction[1]. Fuel economy may also be predicted by the thickening power of a lube oil additive. All the polymers were synthesized by following the method as reported earlier[2] and characterized on the basis
This is achieved either by increasing the shear thickness (intermolecular interactions) of the polymer/oil blend and/or by a globular-to-coil transition (expansion) …
The thickening efficiency is defined by the amount of polymer needed to increase kinematic viscosity and is often recorded as the kinematic viscosity of a blend of a polymer-containing product at a certain weight percent in a standard base oil. For shear stability, most oil and lubricant analysis measure and report the kinematic viscosity ...
Another important metric is thickening efficiency (TE) that describes the amount of polymer (that is, polymer treat rate) required in a lubricant formulation to reach either a desired kinematic viscosity or dynamic viscosity at a temperature of 100 °C [7].
The authors conducted a broad study of the synthesis and application of the different polymer lubricant additives, among ... semi solid lubricants consisting of gelling or thickening agent in a liquid lubricant.

Novethix™ L-10 polymer: Novethix™ L-10 polymer is a hydrophobically-modified alkali-swellable emulsion (HASE) polymer designed for thickening low surfactant systems and providing reduced dripping and misting while maintaining excellent sprayability.
The macromolecular chain architecture [5], [9] and molecular weight of a polymer acts as key parameters in governing thickening efficiency (TE) of the lubricants [10], [11] and polymer with straight structural architecture with narrower molecular weight distribution [12], [13] usually possesses stronger thickening powers.
Thickening efficiencycan be defined as the amount of polymeric additive that must be employed in a lubricant formulation to reach the desired kinematic viscosity at a given temperature, generally at 40 °C. As polymer additives are one of the most expensive components of a lubricant formulation,
The observation that the shear stability performance of polymers in terms of SSI (KV) as compared to SSI (HTHS) could be different, led to the comparing of the thickening. abilities of polymers (percent increase in the viscosity of the base oil with the addition of unit weight of polymer) as determined by these two viscosities (KV and HTHS ...
