| Abstract | ||||
| Poly(δ-valerolactone) (PVL) and its copolymers are currently widely used in medical applications such as drug delivery systems, implants, tissue engineering, and packaging. In the medical field, PVL is one of the most commonly used materials because it is biocompatible, flexible, and non-toxic. To produce PVL, ring opening polymerization (ROP) δ-valerolactone (δ-VL) will be performed using a complex catalyst bis(dibenzoylmethanato)zirconium(IV) chloride (bis(dibzm)2Zr). The advantage of this catalyst is that it can be utilized in the tropics because it is not sensitive to water vapor and air. Moreover, the Lewis acidity of the central atom can also be controlled by varying the electron-withdrawing and electron-donating groups of the ligands. The PVL product characterization in this research was carried out by using FTIR, 1HNMR, 13CNMR, XRD, DSC, and TGA. The obtained PVL is semicrystalline with a low melting point. Thus, the obtained PVL can be applied as a medical material and biodegradable packaging. | ||||
