Lower Critical Solution Temperature in Polyelectrolyte Complex Coacervates. [PDF]
ACS Macro Lett, 2019 A model linear oppositely charged polyelectrolyte complex exhibits phase separation upon heating consistent with lower critical solution temperature (LCST) behavior. The LCST coexistence curves narrow with increasing monovalent salt concentration (C s) that reduces the polymer concentration (C p) in the polymer-rich phase.

Lower critical solution temperatures of polybutadiene solutions
Journal of Polymer Science Part B: Polymer Letters, 1967 Abstract The lower critical solution temperature (LCST) is observed in polymer solvent systems as a rather high temperature above which the solution separates into two phases. This is a relatively recently discovered phenomenon, since it normally occurs above the boiling point of the solvent.

Polymer fractionation at a lower critical solution temperature phase boundary
Polymer, 1966 Abstract The influence of pressure on a lower critical solution temperature is much more pronounced than on an upper critical solution temperature. Accordingly it is possible to control phase separation at a LCST phase boundary under isothermal conditions by merely adjusting the pressure on the system.

eXPRESS Polymer Letters, 2011 One of the most subtle problem in the characterization of thermoresponsive polymers is the evaluation of the relationship between the lower critical solution temperature (LCST) of the linear polymer and the volume phase transition temperature (VPTT) of ...

Modulation of the Lower Critical Solution Temperature of Thermoresponsive Poly(N-vinylcaprolactam) Utilizing Hydrophilic and Hydrophobic Monomers. [PDF]
Polymers (Basel), 2023 Four-dimensional printing is primarily based on the concept of 3D printing technology. However, it requires additional stimulus and stimulus-responsive materials. Poly-N-vinylcaprolactam is a temperature-sensitive polymer.

Polymers for Advanced Technologies, 1996 A series of vinyl polymers with L-valine and L-leucine residues, and related copolymers with N-isopropylacrylamide, were studied in aqueous solution at different temperatures (25, 30 and 35°C) and at two ionic strengths (0.01 M and 0.1 M NaCl). The protonation behavior revealed great differences between the polymers that were attributed to the size of ...

Lower Critical Solution Temperature Behavior in Polyelectrolyte Complex Coacervates. [PDF]
Macromolecules, 2019 In light of recent experimental observations of lower critical solution temperature (LCST) in polyelectrolyte complex coacervates (Ali, S. et al. ACS Macro Lett. 2019, 8, 289-293), we explore its possible mechanisms on the basis of a slight modification of our theory (Adhikari, S. et al. J. Chem. Phys. 2018, 149, 163308). We explore the consequences of
