selective solvent

Two immiscible liquids are sometimes used as selective solvents for components in a mixture.

Collapse of rod-coil copolymers in selective solvents: Single chain nematics, cages and networks.

Collapse dynamics of block copolymers in selective solvents: Micelle formation and the effect of chain sequence.

Asymmetric amphiphilic diblock copolymers self-assemble in selective solvents.

Hydrodynamic radius of micelles of several block copolymers in different selective solvents (for both types of blocks) was determined from photon correlation spectroscopy.

The photon correlation spectroscopy data in combination with intrinsic viscosities of block copolymers in selective solvents were used to determine micellar molecular mass and aggregation number.

The amounts and relative proportions of the selective solvents can modulate the resulting microstructures, although the phase sequence observed depends on the relative PEO–PPO block ratio.

The concept of micelles was introduced to describe the core-corona aggregates of small surfactant molecules, however it has also extended to describe aggregates of amphiphilic block copolymers in selective solvents.

Studying the phase behavior of polystyrene-block-polyisoprene in solvents of varying selectivity, the concept of phase trajectories was introduced to explain the phase sequences observed as a function of concentration in neutral and selective solvents connecting the solution behavior to that seen in block copolymer melts.
