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.
Claims5
A star macromolecule represented by the Formula:
- [(P1)q1]r-Core-[(P3)q3-(P2)q2]s
- wherein:
- Core represents a crosslinked polymeric segment;
- P1 independently represents the hydrophilic polymeric segment of the at least first polymeric arm comprised of monomeric residues of polymerized hydrophilic monomers comprising a mixture of acrylic acid and 2-acrylamido-2-methyl-1-propanesulfonic acid;
- P2 independently represents the further segment of the at least second polymeric arm comprised of at least one monomeric residue of a polymerized surfactant-system thickening monomer;
- P3 independently represents the hydrophilic polymeric segment of the at least second polymeric arm comprised of monomeric residues of polymerized hydrophilic monomers comprising a mixture of acrylic acid and 2-acrylamido-2-methyl-1-propanesulfonic acid;
- q1 independently represents the number of monomeric residues in P1;
- q2 independently represents the number of monomeric residues in P2;
- q3 independently represents the number of monomeric residues in P3;
- r independently represents the number of the at least first polymeric arms covalently attached to the Core;
- and
- s independently represents the number of the at least second polymeric arms covalently attached to the Core.
