Effect of Molecular Weight on Phase Equilibrium in the Polystyrene–Poly(methyl methacrylate) System

open access: yesMolecules, 2023
Data on the solubility of oligomer polystyrene (PS) and poly(methyl methacrylate) (PMMA) of various molecular weights have been obtained. The binodal and spinodal curves of the phase state diagram with the upper critical solution temperature (UCST) are ...

Structure-Property Relationships for n-Alkylamine and Aliphatic Carboxylic Acid-Derived Thermomorphic Multiphase Systems. [PDF]

open access: yesChemSusChem
Systematic investigation of aliphatic amines identified novel thermally switchable solvents and elucidated the physicochemical properties required for their formation. These solvents facilitated efficient and tunable separations, demonstrating that lower critical solution temperature switchable solvents can be prepared from amine‐acid mixtures that are

UCST-Type Thermosensitive Hairy Nanogels Synthesized by RAFT Polymerization-Induced Self-Assembly

open access: yes, 2017
While lower critical solution temperature (LCST)-type thermosensitive nanogels have been intensively studied, the upper critical solution temperature (UCST)-type versions are much less explored.

Tuning the Size of Thermoresponsive Poly(N-Isopropyl Acrylamide) Grafted Silica Microgels

open access: yesGels, 2017
Core-shell microgels were synthesized via a free radical emulsion polymerization of thermoresponsive poly-(N-isopropyl acrylamide), pNipam, on the surface of silica nanoparticles. Pure pNipam microgels have a lower critical solution temperature (LCST) of

INTERDEPENDENCE BETWEEN POINT LOAD INDEX, COMPRESSIVE STRENGTH AND CRUSHING RESISTANCE OF JORDAN OIL SHALE AND RELATION TO CALORIFIC VALUE; pp. 252–268 [PDF]

open access: yesOil Shale, 2015
Rock parameters are important to be considered in mine design. Physical-mechanical tests were carried out on oil shale and dolostone samples from the Attarat Um Ghudran oil shale area in central Jordan, in order to determine the rock mass properties.
