Abstract: Polyurethane urea elastomers with novel dissolution behavior and which are synthesized from polycarbonate macrodiols, diisocyantes and diamines and which can be prepared and dissolved in aqueous solvents. These elastomers have the advantage of being less of a physiological hazard, more resistant to common solvents and require less emulsifiers and dispersion aid.
