Abstract (en)
[origin: WO9418288A1] Viscosity improver capable of imparting a VIE of at least 155 to a lubricating oil exhibiting, before incorporation of the said improver, a viscosity at 100 DEG C of 4.8 to 5.5 mm<2>/s and a VIE of 85 to 100, which exhibits a shear strength such that the relative drop in viscosity after four hours in the "VKA" test or after twenty hours in the "FZG" test is lower than 13 %.
