Highly Active Heterogeneous Double Metal Cyanide Catalysts for Ring-Opening Polymerization of Cyclic Monomers

Chinh-Hoang Tran et al.

Summary: A series of heterogeneous Zn-Co double metal cyanide (DMC) catalysts were investigated for ring-opening polymerization (ROP) of various cyclic monomers. It was found that inexpensive and commonly used organic solvents were effective complexing agents for the preparation of DMC catalysts, which showed high catalytic activity for the ROP of propylene oxide, epsilon-caprolactone, and delta-valerolactone. The chemical structures and compositions of the catalysts were determined using various techniques, and alpha, omega-hydroxyl-functionalized polyether and polyester polyols with high yields and tunable molecular weights were successfully synthesized in the presence of different initiators. Kinetic studies of the ROP of delta-valerolactone were also conducted to confirm the reaction mechanism.

Random Copolymerization of ε-Caprolactone and L-Lactide by Ring Opening Polymerization Using a Co/N-Doped Carbon Framework as Catalyst

Farah Naz et al.

Summary: The synthesis and use of MOF-derived Co/NCF material as a heterogeneous catalyst for copolymers synthesis via ring-opening polymerization (ROP) have been reported for the first time. The Co/NCF material is applied for copolymerization of L-lactides (LA) and epsilon-caprolactone (epsilon-CL) as monomers via ROP in bulk without any solvent or co-catalyst, confirmed by various analytical techniques. Additionally, the copolymer structure was verified through spectroscopic analysis and it was observed that the melting and glass transition temperatures increased with higher LA content, while possessing two phases corresponding to polylactide and polycaprolactone.

Summary: The ZnO dispersed in an N-doped carbon matrix was successfully derived and utilized as a catalyst for the polymerization of E-caprolactone. The catalyst displayed excellent activity and stability, leading to high molecular weight cyclic polycaprolactone.

Ring-opening copolymerization of epsilon-caprolactone and delta-valerolactone by a titanium-based metal-organic framework

Rahaman M. Abdur et al.

Summary: Metal organic frameworks (MOFs) have been investigated as catalysts in copolymer formation with cyclic esters. In this study, a recoverable and reusable Ti-metal based MOF, MIL-125, was used for the ring-opening copolymerization of epsilon-caprolactone (CL) with delta-valerolactone (VL) in a solvent-free medium. The synthesized copolymers are random in nature, exhibit lower crystallinity than those of the corresponding homo-polymers, and are totally free from metal contamination.
