Preferential adsorption and co-nonsolvency of thermoresponsive polymers in mixed solvents of water/methanol

F Tanaka, T Koga, H Kojima, N Xue, FM Winnik - Macromolecules, 2011 - ACS Publications
If two good solvents become poor for a polymer when mixed, the solvent pair is called a co-
nonsolvent pair for the polymer. The sharp depression of the LCST by the co-nonsolvency in …
