Functional Polyesters: Tailoring Structure and Biomedical Functions

Area of Science:

• Polymer Chemistry
• Materials Science
• Biomedical Engineering

Background:

• Aliphatic polyesters are biocompatible and degradable, ideal for medical uses like drug delivery and implants.
• Conventional polyesters are hydrophobic, restricting their use with biomacromolecules (proteins, peptides, nucleic acids).

Purpose of the Study:

• To review research on controlled ring-opening polymerization of functional lactones and O-carboxyanhydrides (OCAs).
• To highlight the development of novel polyesters with tunable functionalities for advanced biomaterials.

Main Methods:

• Controlled ring-opening polymerization of functional lactones.
• Controlled ring-opening polymerization of O-carboxyanhydrides (OCAs).

Main Results:

• Synthesis of novel polyesters with in-chain or side-chain functional groups.
• Achieved defined molar masses and precise locations of functionalities in the resulting polyesters.

Conclusions:

• Functional polyesters offer enhanced properties for biomaterial applications.
• These novel materials show promise for improved drug delivery and implantable devices.
