Abstract
Oil soluble rheology modifying star macromolecules having a core and five or more polymeric arms, and compositions comprising the same. The polymeric arms on a star are covalently attached to the core of the star; each polymeric arm comprises one or more (co)polymer segments; and at least one polymeric arm and/or at least one polymeric segment exhibits a different solubility from at least one other polymeric arm or one other polymeric segment, respectively, in a reference liquid of interest. The oil soluble rheology modifying star macromolecules and compositions comprising the same for use in oil based systems.
