Abstract:

The concentration dependences of the mean and partial enthalpies of PMMA mixing with chloroform, DMF, ethyl acetate, acetone, acetonitrile, and toluene at 298 K were studied by calorimetry in the entire composition range. PMMA interacts more strongly with acceptor solvents than with donor solvents. The mean molar enthalpies of interaction at 298 K were calculated for all the systems examined, taking into account the glassy state of PMMA. It was shown that heat is evolved on interaction of PMMA with chloroform. In contrast, heat is absorbed on interaction of PMMA with DMF, acetone, acetonitrile, and toluene. The results are explained by possible hydrogen bonding in solutions or by formation of stereocomplexes and associates between the PMMA chains and the solvent molecules.
