Syntheses and Drug Delivery Property of Biodegradable Polyether-Anhydrides

Both pofyanhydrides and polyethers are new types of biodegradble polymers. They are of particular interest as materials for controlled drug release systems duo to their excellent surface erosion properties of poly-anhydrides and excellent biocompatibility of polyethers. They have been widly used in biomaterials. A series of polyether anhydrides elastomer were firstly synthesed through introducing PEG into the pofyanhydrides chains.Their degradation and drug release property were also studied.These materials may be used in applications wherematerials are needed with properties more close to those of natural skin.
