WEAR-INHIBITION BY ADSORPTION OF POLYMERIC SOLUTION

Polymers used as viscosity index improvers contribute to the wear-inhibition of multigrade engine oils. Investigations with the model oil of poly (n-butylmethacrylate) in different solvents as basic oil show that friction and wear are depending on state of solvation of the macromolecules, the adsorption of the polymer from solution on solid surface and the heat of wetting of the solvents on iron (Fe). The results are interesting for praxis.
