ABSTRACT:
Neopolyol derivatives in which at least one of the hydroxyl groups is replaced with a substituent that corresponds to the formula --O--R--C(O)--OR' wherein R is an alkylene group containing 2-5 carbons and R' is a hydrocarbyl or predominantly hydrocarbyl group containing 1-30 carbons are oils which have utility as lubricants. Those in which R' is a hydrocarbyl group of 1-10 carbons are completely miscible with 1,1,1,2 -tetrafluoroethane (R-134a), a refrigerant.
