Abstract
Barium- and lead- containing polyurethanes were synthesized. The chemi cal bonding of metals was confirmed by IR spectroscopy. The effect of metal ions on the microstructure of polymers was measured by different ial scanning calorimetry and dynamic mechanical spectroscopy. The stru cture of ion-cured polymers was found to be determined not by the type of metal-polymer bonding, but by the ability of metal ions to partici pate in additional donor-acceptor interactions. For some systems the e nergy of these interactions can exceed the energy of the metal-polymer ionic bonds.
