Li, Min;Zhang, Pan;Chen, Changle published 《Light-Controlled Switchable Ring Opening Polymerization》 in 2019. The article was appeared in 《Macromolecules (Washington, DC, United States)》. They have made some progress in their research.Reference of Oxacyclohexadecan-2-one The article mentions the following:
Salicylaldimine Zn(II) complexes bearing azobenzene moieties were prepared and characterized. Isomerization between the trans and cis forms of these complexes was achieved by exposure to light; both isomers were active in ring-opening polymerizations of ε-caprolactone (CL), rac-lactide, trimethylene carbonate, β-oxetanone, δ-valerolactone, cyclopentadecanolide, and 5-methyl-5-propyl-1,3-dioxan-2-one but exhibited different kinetic profiles. A 6-fold reactivity difference was realized for the ring-opening polymerization of CL upon irradiation with light. The light-induced isomerization also led to reactivity discrimination between different monomers in copolymerization reactions. Reversible photoswitching between two catalytically active states provides a strategy for the control of polymerization processes, as well as the compositions of the polymers produced. The experimental procedure involved many compounds, such as Oxacyclohexadecan-2-one (cas: 106-02-5) .
Oxacyclohexadecan-2-one(cas:106-02-5) is a monomer used to make PGA-co-pentadecalactone polymers to be used in the development of directly compressed prolonged release tablets of slightly soluble drugs such as ketoprofen.Reference of Oxacyclohexadecan-2-oneIt may be used for the synthesis of poly(pentadecanolide) (PPDL) by Novozyme 435 catalyzed ring-opening polymerization.
