摘要: A gear oil composition is provided, the composition comprising a hydrogenated star conjugated diolefin polymer having arms with weight average molecular weights between about 3,000 and about 15,000. Such star polymers are effective as viscosity index improvers, and yet are sufficiently shear stable for service in gear oil lubricants.
