Over the last 60 years, polyolefin-based plastics have considerably been developed to become the most used materials today. However, they are made from non renewable fossil resources and pose an environmental problem (waste storage, pollution...). As a consequence, biodegradable and biocompatible polymers may be a viable alternative to petrochemical-based plastics. As a result, biodegradable aliphatic polyesters and polycarbonates have received increasing attention over the last years. They can be obtained by the ring-opening polymerization (ROP)of cyclic monomers. In the present book, the...
