Abstract :

Aliphatic polyesters are commonly applied in bio-medical engineering for drug delivery devices and tissue engineering products because of their biodegradable and biocompatible properties. Unsaturated aliphatic polyesters, such as poly(�±methylene-�³-butyrolactone) (PMBL), are of scientific and technological interest for producing tailor-made functionalized biodegradable shape memory materials due to their exocyclic alkene functionality. Cross-linking in biodegradable polymers, like hydrogels, usually produces shape memory polymers that are sensitive to their environment. Due to unfavourable thermodynamics involved in the ring-opening polymerization (ROP) of MBL, which is from its low strain energy of the fivemembered lactone ring that brings about too small negative change of enthalpy (��H) to offset a large negative entropy change (��S) of its ROP, MBL prefers vinyl addition polymerization to ROP. Therefore, ring-opening homo polymerization of MBL and developing an effective cross-linking strategy will provide a gateway into a smart biodegradable polymeric material for shape-memory applications.
