Effect of PAO Polymerization Degree on the Structure and Elevated-Temperature Tribological Performance of Preformed Polyurea Greases

Conventional poly-α-olefin (PAO) base oils are widely used in grease formulations, but how their degree of polymerization affects oil-phase confinement and release within polyurea thickener networks at elevated temperatures remains unclear. Here, PAO20, PAO40, and PAO100 were used to prepare PGA, PGB, and PGC, respec...
