Polyanhydrides

• Polyanhydrides are a class of biodegradable polymers characterized by anhydride bonds that connect repeat units of the polymer backbone chain.
• Their main application is in the medical device and pharmaceutical industry.
• In vivo, polyanhydrides degrade into non-toxic diacid monomers that can be metabolized and eliminated from the body.
• Owing to their safe degradation products, polyanhydrides are considered to be biocompatible.
