Synthesis and properties of polyurethanes containing phosphatidylcholine analogues in the polymer backbone

Abstract

Abstract New polyurethanes ( 4a, 4b ) and a segmented polyurethane ( 4c ) bearing phosphatidylcholine moieties in the main chain were synthesized. They are thermally stable up to 300°C and show the viscosity behaviour of common polyelectrolytes. Preliminary studies suggest that these polyurethanes are interesting new biomaterials.
