Usage & Core Function of Delta-Valerolactone Monomer
(Bio-Based Building Block for Polymer Development)
- Monomer for Biodegradable Polymers
Delta-Valerolactone monomer is used in ring-opening polymerization to produce poly(δ-valerolactone) (PVL), a biodegradable and biocompatible polyester. PVL and its copolymers are employed in medical devices, tissue engineering scaffolds, and controlled-release drug delivery systems due to their flexibility and safe degradation profile.
- Co-Monomer for Copolyesters and Polyurethanes
It is also widely used as a co-monomer in the production of soft-segment polyurethanes and polyesters, enhancing elasticity, toughness, and low-temperature performance in elastomeric applications.
- Advanced Functional Polymers
The monomer is suitable for functionalization, enabling the creation of reactive polymer chains for specialty applications such as adhesives, thermoplastics, and bio-based thermoset materials.
- Bio-Compatible Medical Polymers
Thanks to its purity and low toxicity, delta-Valerolactone is considered safe for biomedical applications, including biodegradable implants and surgical sutures.
