PURPOSE:To obtain the title composition excellent in the compatibility with hydrogen-contg. CFC refrigerants such as CFC-134a, lubricity and wear resistance, esp. useful in Al-steel material interface by incorporating a specific polyester compound with a specific chlorinated arylphosphate. CONSTITUTION:The objective composition can be obtained by incorporating (A) a polyester compound 5-1000 (pref. 1-500)cSt in the kinematic viscosity at 40 deg.C having two or more ester linkages with (B) pref. 0.1-10 (esp. 1-5)wt.% of a chlorinated arylphosphate of the formula (R is H or 1-12C alkyl; x and y are each integer 1-3, and x+y<=5). |
