Biodegradable polymer

Example of cutlery made from biodegradable plastic

Example of routes to polyester formation using lactic acid. a) Condensation of lactic acid into dimeric lactide followed by ring-opening polymerization of to form poly(lactic acid); b) Direct condensation of lactic acid, demonstrating the need to continuously remove water from the system in order to drive the reaction forward.[14]

Sutures made from polyglycolic acid. These sutures are absorbable and will be degraded by the body over time.

Biodegradable polymers are a specific type of polymer that breaks down after its intended purpose to result in natural byproducts such as gases (CO₂, N₂), water, biomass, and inorganic salts. These polymers are found both naturally and synthetically made, and largely consist of ester, amide, and ether functional groups. Their properties and breakdown mechanism are determined by their exact structure. These polymers are often synthesized by condensation reactions, ring opening polymerization, and metal catalysts. There are vast examples and applications of biodegradable polymers.
