摘要：
A grease composition having improved water resistance is disclosed. More specifically, the addition of a copolymer of ethylene and at least one other alpha-olefin monomer and an ethylene copolymer having an amine functionality to a base grease comprising a lubricating oil and a water insoluble thickener results in a grease composition which has excellent water resistance. In a preferred embodiment, polyisoprene is added to obtain a further improvement in water resistance.
