Abstract
The lubricant film thicknesses of a number of polymer-containing oils and their base oils were measured systematically in a twin-disk test rig. In addition, the base oil viscosity and the concentration of the polymers in the base oil were varied. All polymer-containing oils formed lower film thicknesses than a straight mineral oil of the same kinematic viscosity over a wide range of operating conditions. As a result, short-chain polymers in high concentration in the base oil turned out to be significantly more effective in the contact than long-chain polymers in low concentration with the same viscosities.
