Abstract
The solution properties of polyurethanes (PU) and PU ionomers of different compositions will be investigated in solvents of different polarity with and without the addition of an electrolyte. Relative molar mass averages will be determined by SEC, absolute molar mass averages and dimensions by SEC-MALS and LS, and the second virial coefficients by LS. LS and viscometry will be used to investigate the influence of the content of ionic groups and the kind of counterion on the extent and type of association of PU ionomers in THF and on the extent of the polyelectrolyte effect in DMF.
