    Abstract:
    Polyurethane has been extensively studied and widely used as a biomedical material since the early 1960s. We have been designing biodegradable polyurethanes that contain a phosphorus ester linkage in the backbone to induce biodegradability and to link bioactive agents directly to the phosphorus atom. In this communication, we extend this study to polyurethanes which contain phospholipids in the side chain. Furthermore, with the objective of obtaining a polymer that would break down into non-toxic products, a lysine-based diisocyanate and a biodegradable chain extender are used for the polyurethane synthesis.
