Abstract
The present invention relates to a composition comprising at least one sulfonated surfactant composition and one or more multi-arm star macromolecules having a core and a plurality of polymeric arms, and methods of preparing and using the same. In one aspect of the invention, this composition is capable of increasing the viscosity, and/or temperature-stability to an aqueous system.
Claims19
A composition comprising at least one sulfonated surfactant composition and one or more star macromolecules having a core and a plurality of polymeric arms, wherein:
- a) at least one polymeric arm of the plurality of polymeric arms is a hydrophilic polymeric arm;
- b) at least one polymeric arm of the plurality of polymeric arms is a copolymeric arm, wherein the at least one copolymeric arm:
- 1) comprises a longer hydrophilic segment proximal to the core and a shorter hydrophobic segment distal to the core;
- and
- 2) has a greater degree of polymerization than the at least one hydrophilic polymeric arm;
- and
- wherein the at least one sulfonated surfactant composition comprises a disulfonated surfactant composition represented by Formula II or Formula III:
- wherein:
- R1 —represents a hydrogen, or a linear or branched C6-C24 alkyl;
- R2 —represents a hydrogen, or a linear or branched C6-C24 alkyl;
- R3 —represents a hydrogen, or a linear or branched C6-C24 alkyl;
- M—represents an alkali metal, an ammonium represented by N(R4)4, or an aminoalcohol, or SO3M is SO3H;
- wherein R4 independently represents a hydrogen, or a linear or branched C3-C6 alkyl;
- m—represents an integer of 1 or 2;
- and
- n—represents an integer of 0 or 1;
- and
- wherein at least one and no more than two of R1, R2, and R3, represents a linear or branched C6-C24 alkyl.
