Biodegradation is the natural process by which organic chemicals in the environment are converted to simpler compounds, mineralized and redistributed through elemental cycles. Biodegradation can occur within the biosphere and micro organisms play a central role in the biodegradation process. A polymer material is called biodegradable if all its organic components undergo a total biodegradation. Hydrolysable polymers such as poly esters are often more prone to degradation but at the same time are often less suitable than hydrophobic polymers for many technical applications. Aliphatic homo polyesters such as poly (tetra methylene adipate (PTMA) and block copolymers such as poly (ethylene succinate)-b-poly (ethylene glycol) (PES/PEG) and poly (ethylene succinate)-b-(tetra methylene glycol) (PEG/PTMG) have been synthesized and the materials obtained showed thermoplastic elastomer behavior. The synthetic hydrolysable poly anhydrides are useful to biomedical applications due to the fiber forming properties. The aliphatic polycarbonate is useful as a biodegradable polymer for medical applications which displays hydrolytic degradation.
