The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a tetrafluoropropene and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.

Disclosed are lubricating compositions and base oils for motor vehicles, specifically for engines, gearboxes, or vehicle axle assemblies. The lubricating composition contains an oil-soluble polymer that is a specific polyalkyl glycol or a specific polyalkylene glycol (PAG). Also described is use of the lubricating composition for reducing fuel consumption in a vehicle provided with an engine, an axle assembly, or a gearbox that are lubricated using the lubricating composition or the specific PAG.

The refrigerator oil according to the present invention includes a base oil including an oxygen-containing organic compound and a phosphorus-based compound represented by the following general formula (1). ##STR00001## In the formula (1), n represents an integer of 1 to 10; R.sup.1 to R.sup.8 each independently represent a hydrogen atom or an alkyl group having 1 to 20 carbon atoms; and Ar represents a divalent hydrocarbon group having 2 to 20 carbon atoms.

Disclosed herein are star-shaped macromolecular structures comprising a hyper-branched silicon containing core grafted with a well-defined and controllable number of alkyl (methyl)acrylate (co)polymer arms. The presence of the robust inorganic core provides additional resilience against mechanical degradation and therefore enhanced additive life time. Control over the additive architecture was complemented by tunability of the length of the grafted polymers by making use of controlled radical based polymerization techniques. The performance of these novel inorganic-organic star-shaped hybrids were compared to traditional fully organic lubricant additives. Detailed analysis revealed the multi-functional character of the hybrids by simultaneously performing as bulk viscosity modifiers, boundary lubricant, and wear protectants while being dispersed in a commercially available base oil for automotive lubrication purposes.

A refrigerator oil according to one embodiment of the present invention contains: a base oil containing an oxygen-containing organic compound; a polyphosphate ester compound; and a benzotriazole compound.
