    Abstract: A fluid composition comprises a base stock and a polymer. The base stock comprises a glycol, such as ethylene glycol. The polymer comprises the reaction product of a hydroxyl functional initiator, such as a diol, and alkylene oxides. The alkylene oxides are selected from the group of ethylene oxide (EO), propylene oxide (PO), and butylene oxide (BO). In certain embodiments, the alkylene oxides comprise EO and PO. The fluid composition provides a four-ball wear test scar of less than about 1 millimeter, generally under the following test conditions: 60 minutes run, 55° C., 1800 rpm, and 40 kg load. In other embodiments, the fluid composition comprises the polymer and is substantially free of the base stock. The fluid composition is useful for vibration dampening and can be used in vibration dampeners. The vibration dampener is useful for dampening vibrations between the two rigid components of the vehicle.

    Abstract: A lubricant composition includes a biodegradable polyalkylene glycol, an inherently-biodegradable polyalkylene glycol, and a non-biodegradable polyalkylene glycol. The biodegradable polyalkylene glycol satisfies the biodegradability requirements set forth in OECD 301B. The inherently-biodegradable polyalkylene glycol satisfy the inherently-biodegradability requirements set forth in OECD 301B. The non-biodegradable polyalkylene glycol is defined by OECD 301B and satisfies the non-bioaccumulative requirements set forth in OECD 107. The lubricant composition includes the biodegradable polyalkylene glycol in an amount of at least about 30 parts by weight, the inherently-biodegradable polyalkylene glycol in an amount of from about 0.1 to about 10 parts by weight, and the non-biodegradable polyalkylene glycol in an amount of from about 0.1 to about 5 parts by weight, each based on 100 parts by weight of the lubricant composition.
