Phosphate based biodegradable polymers |
摘要 |
Featured are biodegradable polymers comprising repeat units derived from cyclic phosphate monomers and optionally further comprising repeat units derived from lactide or caprolactone monomers. Also featured are methods for preparing the biodegradable polymers of the invention and biodegradable polymer compositions comprising a biologically active substance and a biodegradable polymer. Additionally featured are articles and microspheres prepared from biodegradable polymers and polymer compositions of the invention. Further, methods for the controlled release of a biologically active substance using the biodegradable polymers of the invention are also described.
