    摘要: A lubricant composition may include a copolymer having constitutional units formed from monomers including an alpha-olefin and an α-ester-alk-ω-ene molecule, where the composition has a kinematic viscosity at 100° C. of at most 20 centistokes, or of at least 40 centistokes. A lubricant composition may include a copolymer having constitutional units formed from monomers including an alpha-olefin, an α-ester-alk-ω-ene molecule and an α-(carboxylic acid)-alk-ω-ene molecule, where the composition has a viscosity that varies as the molar ratio of the α-ester-alk-ω-ene molecule α-(carboxylic acid)-alk-ω-ene molecule in the monomers varies.

    摘要: The present invention provides a highly stable HFO refrigerant composition for use in a vapor compression-type refrigeration system, having improved slidability for the sliding portions of the vapor compression-type refrigeration system. More specifically, the present invention provides an HFO refrigerant composition comprising at least one type of HFO refrigerant and a polymer of halogenated propene represented by C3HaFbClc (provided that a+b+c=6, a=an integer of 1 to 3, b=an integer of 3 to 5, and c=an integer of 0 to 1) that is an oligomer having a molecular weight of 200 to 900.
