Phase transformations in aqueous low molar mass poly(vinyl methyl ether) solutions: Theoretical prediction and experimental validation of the peculiar solvent melting line, bimodal LCST, and (adjacent) UCST miscibility gaps

Several experimental and theoretical predictions based on the modulated temperature differential scattering calorimetry are used to study the phase transformations in aqueous low molar mass poly(vinyl methyl ether) solutions. The process used is extremely sensitive towards the measuring board and confirms all the observed properties like the solvent melting line, bimodal lower critical solution temperature (LCST), as well as the upper critical solution temperature (UCST) miscibility gaps.
