Outline of Final Research Achievements |
Purpose on this research is to design new efficient molecular catalysts for olefin polymerization/oligomerization including synthesis of new polymers by precision polymerization. We demonstrated synthesis of new cyclic olefin copolymers (highly transparent, thermal resistant) in precise polymerization using half-titanocene catalysts. We also succeeded in design of new efficient (thermally robust) vanadium-alkylidene complex catalysts which exhibit remarkable catalytic activities for ring-opening metathesis polymerization of various cyclic olefins. (Imido)vanadium complex catalysts containing WCA-NHC ligand exhibited remarkable catalytic activities for ethylene polymerization in the presence of Al(i-Bu)3 instead of MAO; this should also be the remarkable effort in terms of development of green sustainable polymerization process. Efficient incorporation of reactive functionalities into the polymer chain is also an interesting approach for synthesis of functionalized polyolefin.
