1. A polymer composition comprising one or more star macromolecules formed by an arm-first living-controlled radical polymerization and having a core and a plurality of polymeric arms, wherein:
- a) at least one arm of the plurality of polymeric arms is a hydrophilic polymeric arm, and at least one arm of the plurality of polymeric arms is a copolymeric arm, wherein;
1) the copolymeric arm comprises a longer hydrophilic segment proximal to the core and a shorter hydrophobic segment distal to the core; and
2) the hydrophilic polymeric arm is shorter than the copolymer arm.

Abstract
A polymer composition comprising star macromolecules is provided. Each star macromolecule has a core and five or more arms, wherein the number of arms within a star macromolecule varies across the composition of star molecules. The arms on a star are covalently attached to the core of the star; each arm comprises one or more (co)polymer segments; and at least one arm and/or at least one segment exhibits a different solubility from at least one other arm or one other segment, respectively, in a reference liquid of interest.
