Biological-based polyurethanes and methods of making the same. The polyurethanes are formed by reacting a biodegradable polyisocyanate (such as lysine diisocyanate) with an optionally hydroxylated biomolecule to form polyurethane. The polymers formed may be combined with ceramic and/or bone particles to form a composite, which may be used as an osteoimplant.
La présente invention concerne des polyuréthanes à base biologique et des procédés de fabrication correspondants. Ces polyuréthanes sont formés en faisant réagir un polyisocyanate (tel qu~un diisocyanate de lysine) avec une biomolécule optionnellement hydroxylée pour former le polyuréthane. Les polymères formés peuvent être combinés avec des particules de céramique et/ou d~os pour former un composite qui peut être utilisé comme prothèse osseuse.
