Transition-Metal Catalysts for Olefin Metathesis and Ethylene Polymerization
This community develops metal-based catalysts to build, modify, and recycle polyolefins and other polymers through metathesis and ring-opening reactions.
The work centers on designing ligands for nickel, ruthenium, palladium, and titanium complexes to control polymerization of ethylene, propylene, and cyclic monomers. Key methods include olefin metathesis, ring-opening metathesis polymerization, and radical polymerization. Researchers focus on tuning molecular weight, copolymerization with polar monomers, and creating functional polyethylenes. Recent efforts also address the chemical recycling of polyethylene and polylactic acid, as well as the synthesis of biodegradable polymers like polycaprolactone.
The largest share of the community's output is found in ruthenium research, accounting for 9.0% of all ruthenium studies, and 3,164 papers here. This is followed by molybdenum and tungsten, each representing 5.0% of their respective element research.
The community comprises 17,933 papers, published primarily in Organometallics, the Journal of Organometallic Chemistry, and the Journal of the American Chemical Society.
Recent work includes nickel-catalyzed olefin copolymerization with polar monomers, sustainable polyolefin synthesis and recycling, and the development of chemically recyclable multiblock copolymer adhesives.
