Abstract: The present invention provides a fluorine-containing ether compound that can form a lubricating layer which has excellent wear resistance even if the thickness is thin and in which a decrease in film thickness due to spin-off is less likely to occur. The fluorine-containing ether compound is represented by the following formula. R1—R2—O—CH2—R3—CH2—O—R4—R5 (R3 is a perfluoropolyether chain. R1 and R5 are either an alkyl group which may have a substituent or a hydrocarbon group having a double bond or triple bond. R2 and R4 are each a divalent linking group containing one or more heteroatoms, and have one or more polar groups, and the terminal end on the side bonded to R1 and R5 is a heteroatom. At least one of R2 and R4 contains one or more secondary amine structures. At least one of R1—R2— and —R4—R5 contains one or more cyano groups).

Abstract: A compressor is a compressor for a refrigeration cycle apparatus that performs a refrigeration cycle using a refrigerant containing a hydrofluoroolefin and a refrigeration oil containing a polyol ester or a polyvinyl ether. The compressor includes a sliding portion. The sliding portion is formed of an aluminum alloy containing from 5 wt % to 25 wt % of silicon. The refrigeration oil contains an acid scavenger or an oxygen scavenger and satisfies the following relational formula: total content (wt %) of acid scavenger and oxygen scavenger in refrigeration oil≥(2.3+2.6×(hydrofluoroolefin content (wt %) in refrigerant)−1.6×(silicon content (wt %) in sliding portion))/100.

The lubricating oil composition is used for gas engines and contains a base oil (A), at least one ash-free additive (B) selected from an ash-free sulfur-based antioxidant (B1) and a hindered amine compound (B2), and a boronated imide-type dispersant (C), and satisfies the following requirements (X1) to (X3): Requirement (X1): the sulfated ash content is 0.2% by mass or less. Requirement (X2): the content of the ash-free additive (B) is 1.2% by mass or less based on the total amount of the lubricating oil composition, provided that in the case where the ash-free additive (B) contains the hindered amine compound (B2), the content of the hindered amine compound (B2) is less than 1.0% by mass based on the total amount of the lubricating oil composition. Requirement (X3): the content of the boron atom derived from the boronated imide-type dispersant (C) is 200 ppm by mass or more based on the total amount of the lubricating oil composition.

Abstract: Embodiments herein relate to polyacrylic acid containing lubricious coatings for medical devices. In an embodiment, a lubricious coated medical device is included having a substrate and a first layer disposed over the substrate. The first layer can include a photoreactive polyvinylpyrrolidone, a non-photoreactive polyvinylpyrrolidone, and a crosslinking compound. A second layer can be disposed over the first layer, the second layer can include a poly(acrylic acid), and a non-photoreactive polyvinylpyrrolidone. The non-photoreactive polyvinylpyrrolidone of the second layer forms a complex with the poly(acrylic acid) of the second layer. The non-photoreactive polyvinylpyrrolidone of the second layer has a concentration existing as a gradient through a thickness of the second layer with a lower concentration at an outer surface of the second layer than at an inner surface of the second layer.
