Abstract: A grease composition, having improved water resistance, adhesion and low temperature pumpability properties, which comprises
(a) from 50 to 98 wt%, based on grease, of a lubricating oil; (b) from 1 to 30 wt%, based on grease, of a thickener; and (c) from 0.5 to 2.0 wt%, based on grease of polymer selected from either a defined block copolymer of the structure A-B, or a hydrogenated star-shaped polymer having a poly(divinylbenzene) nucleus and at least seven hydrogenated polyisoprene arms linked to said nucleus. The grease has an apparent viscosity of less than about 3500 poise (350 Pa.s) at 20 sec⁻¹.
