摘要：A fluid composition comprises a base stock and a polymer. The base stockcomprises a glycol, such as ethylene glycol. The polymer comprises the reaction productof a hydroxyl functional initiator, such as a diol, and alkylene oxides. The alkylene oxidesare selected from the group of ethylene oxide (EO), propylene oxide (PO), and butyleneoxide (BO). In certain embodiments, the alkylene oxides comprise EO and PO. The fluidcomposition provides a four-ball wear test scar of less than about 1 millimeter, generallyunder the following test conditions: 60 minutes run, 55°C, 1800 rpm, and 40 kg load. Inother embodiments, the fluid composition comprises the polymer and is substantiallyfree of the base stock. The fluid composition is useful for vibration dampening and can beused in vibration dampeners. The vibration dampener is useful for dampening vibrationsbetween the two rigid components of the vehicle.
