Beschreibung
Zusammenfassung:	The disclosed technology relates to a lubricant composition containing a polyalkylene glycol in which greater than 50% of the repeating units in the polyalkylene glycol contain an alkylene oxide derived moiety comprising a C4 or greater alkyl group. The lubricant compositions are particularly useful in compressors, such as a reciprocating rotary vane, scroll, or rotary screw air compressor. La technologie ci-décrite concerne une composition de lubrifiant contenant un polyalkylène glycol dont plus de 50 % des motifs à répétition contiennent un fragment dérivé d'oxyde d'alkylène comprenant un groupe alkyle C4 ou supérieur. Les compositions lubrifiantes selon l'invention sont particulièrement utiles dans les compresseurs, tels qu'un compresseur d'air à pistons, rotatif à palettes, de type spiro-orbital dit "Scroll", ou rotatif à vis.
