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

摘要

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℃ and show the viscosity behaviour of common polyelectrolytes. Preliminary studies suggest that these polyurethanes are interesting new biomaterials.
