摘要：
The present invention provides a composition for use in refrigeration and air-conditioning comprising: (a) at least one refrigerant selected from the group consisting of hydrofluorocarbon, hydrochlorofluorocarbon, fluorocarbon, and chlorofluorocarbon; and (b) a sufficient amount to provide lubrication of at least one polyoxyalkylene glycol. The polyoxyalkylene glycol has at least one pendant non-terminal perfluorinated alkyl group on its hydrocarbon polymer backbone. The polyoxyalkylene glycol is terminated with a group selected from the group consisting of hydrogen, alkyl, and fluoroalkyl. The polyoxyalkylene glycol has a molecular weight of about 300 to about 4,000 and a viscosity of about 5 to about 300 centistokes at 37.degree. C. The polyoxyalkylene glycol is miscible in combination with the refrigerant in the range between about -40.degree. C. and at least about +20.degree. C.
