Abstract
A grease composition having improved water resistance is disclosed. More specifically, the addition of 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 enhanced water resistance relative to a grease containing an ethylene copolymer without amine functionality.
