Abstract:

Dissolution of PAA in various donor and acceptor solvents was studied at 273-423 K. A phase diagram with LCST was obtained for PAA-THF system. Mean specific enthalpy of mixing and partial excess enthalpy of the solvent were determined by calorimetry for the solutions of PAA in water, the acceptor solvent (butanol), or the donor solvent (DMF), over the entire range of compositions and at different temperatures. Similar data were also obtained for aqueous solutions of poly(methacrylic acid) as the closest PAA homolog. PAA more readily interacts with the donor compounds than with the acceptor ones. In contract to the other solutions studied, the PAA-water system is characterized by abnormal extrema in the concentration dependences of the partial excess enthalpy of water, The results are discussed in terms of specific features of solvation and association processes in PAA solutions.
