|Outline of Final Research Achievements
Purpose on this project is to design efficient molecular catalysts for precise olefin polymerization and selective ethylene oligomerization including synthesis of new polymers by precision polymerization. We demonstrated various efficient catalysts (half-titanocenes, vanadium, and niobium complexes) for the purpose, and successful synthesis of new ethylene copolymers with aromatic vinyl monomers, low strained cyclic olefins etc. We also demonstrated new efficient niobium-alkylidene catalysts for living metathesis polymerization of internal alkynes, and vanadium-alkylidene catalysts for ring-opening metathesis polymerization.
