[origin: EP0344307A1] Fluid is prepd. by blending 0.1-70 wt.% of branched poly-alpha-olefin with a diester cpd. of formula (I) or its derivs. In (I) A' is -COO- or -OOC-; n = 1-6; R1 is one or more of H or 1-8C alkyl gps.; R2 is one or more of 1-3C alkyl gps. The blend ratio of poly-alpha-olefin is 10-50 wt.% and its ave. mol. wt. is 500-10,000. Pref. the poly-alpha-olefin is polybutene. Pref. diester cpds. are those where R1 is one or more of H and 1-4C alkyl gps., n = 1-3, and R2 being CH3.
