Synthetic aero - lubricant base stocks have excellent lubricating property, viscosity and temperature property, high temperature stability and low temperature flowing property, anti-oxidative property and volatility property. They have been widely utilized because significant advantages to satisfy the development of aero-engine. It was introduced and contrasted the properties of two aero -lubricant base stocks, poly α -olefins ( PAO) and esters, and the thermal degradation mechanisms of these two kinds of base stocks were described.
