Poly(α-methylene-γ-butyrolactone) as potential smart polymeric material for healthcare
applications

A
liphatic 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(α-
methylene-γ-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 five-
membered lactone ring that brings about too small negative change of enthalpy (ΔH) to offset a large negative entropy change
(ΔS) 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.
