Transition-Metal Catalysts for Olefin and Ring-Opening Polymerization
This community designs and characterizes metal complexes that catalyze the conversion of small molecules into polymers, specifically focusing on olefin polymerization and the ring-opening polymerization of cyclic esters and ethers.
The work centers on the synthesis of ligands and metal complexes—predominantly nickel, titanium, and rare-earth elements—to control polymer structure, molecular weight, and reactivity. Recurring themes include the development of highly active catalysts for ethylene oligomerization and copolymerization, as well as the study of chain transfer and electronic structure in coordination chemistry. Specific applications named in the literature include the production of polyolefins, thermoplastic elastomers, and biodegradable materials such as polycaprolactone and polyhydroxyalkanoates. The research emphasizes precise control over polymer microstructure, including stereoregularity and functionalization, to tailor material properties for industrial use.
The community is most heavily represented in uranium research, accounting for 3.4% of all uranium-related papers, and zirconium research, at 2.0%. It also constitutes a significant portion of titanium research, with a 1.3% share.
The community comprises 37,056 papers, published primarily in Organometallics, Inorganic Chemistry, and the Journal of Organometallic Chemistry.
Recent work continues to focus on nickel-catalyzed olefin copolymerization with polar monomers and the development of catalysts for high-temperature solution processes. Other recent studies address the synthesis of functionalized polyethylenes with photodegradable groups and the investigation of rare-earth complexes for luminescent applications.
