Outline of Final Research Achievements |
Purpose on this project is design and synthesis of new efficient catalysts in precise olefin polymerization for synthesis of new polymers with specified functions, including development of new synthetic methodology for (polar) functionalized polyolefins under mild conditions. The imidazolidin-2-iminato modified halt-titanocenes exhibited unique characteristics for the purpose; Cp* analogues showed exceptionally high activities in ethylene/alfa-olefin copolymerization. The ligand modifications are important for exhibiting notable activities and efficient comonomer incorporation. Precise synthesis of functionalized polymers by efficient incorporation of reactive functionality by copolymerization of ethylene with nonconjugated diene or divinyl-biphenyl has been achieved by using phenoxy-modified half-titanocene catalysts. We also demonstrated new type of olefin polymerization catalysts, Ti-Al hetero-bimetallic complexes, that would reduce Al cocatalyst in the polymerization process.
