Solution properties and characterization of polyisoprenes at a lower critical solution temperature (LCST)

Polymer, 1989
Abstract This paper reports two investigations on polyisoprene. One consists of obtaining the molecular weight distribution (MWD) of cis -polyisoprene (PIP) standards by a new method using the turbidity at a lower critical solution temperature (LCST).

RNAs undergo phase transitions with lower critical solution temperatures

Nature Chemistry, 2022
Abstract Co-phase separation of RNAs and RNA-binding proteins is thought to drive the biogenesis of ribonucleoprotein granules. RNAs can also undergo phase transitions in the absence of proteins. However, the physicochemical driving forces of protein-free, RNA-driven phase transitions remain unclear.

Dynamical heterogeneity in the gelation process of a polymer solution with a lower critical solution temperature

Soft Matter, 2021
The gelation of a hydrophobically modified hyaluronic acid aqueous solution which shows a lower critical solution temperature of about 25 °C was investigated by multi-particle tracking microrheology.

Upper and Lower Critical Solution Temperatures in Polystyrene Solutions. II

Macromolecules, 1973
Abstract Upper and lower critical solution temperatures have been determined for solutions of polyethylene in n-butyl acetate and n-amyl acetate over the molecular weight range of M η = 1·36 × 10 4 to 17·5 × 10 4 . Polyethylene solution in n-butyl acetate displays a smaller miscibility region than that of the polyethylene/n-amyl acetate system,

Lower and upper critical solution temperatures of binary polymeric solutions

Fluid Phase Equilibria, 2016
Abstract The phase behavior of binary polymeric solutions such as lower and upper critical solution temperatures has an important role in many polymeric processes. For theoretical investigation on the prediction of these temperatures, a substantial number of data points on binary polymeric solutions were collected from literature and used to present ...

A comparison of lower critical solution temperatures of some polymer solutions

Polymer, 1967
Abstract The Lower Critical Solution Temperature (LCST) in polymer solutions is discussed in terms of the Prigogine solution theory which predicts an LCST below the vapour-liquid critical temperature of the solvent (T c ). The interval between these two temperatures depends on differences in chain length and ‘flexibility’ of the polymer and 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.
