Design of Efficient Molecular Catalysts for Precise Olefin Polymerization
Polyolefins such as polyethylene, polypropylene are widely used in our daily life, and use of polyolefins should be favored not only because the recycling is easier than other specified (functionalized) polymers, but also because syntheses of the monomers are simple with short steps. Designing efficient metal complex catalysts for precise olefin polymerization is one of the most attractive subjects, because evolution of new polymers that have not been prepared by ordinary catalysts can be highly expected by designing the new catalysts. Nonbridged half-metallocene type titanium complexes containing anionic donor ligand (L) of the type, CpTi(L)X2 (Cp: cyclopentadienyl group; X: halogen, alkyl etc.), are promising candidates, because these complex catalysts demonstrated unique characteristics as olefin polymerization catalysts that had never been achieved by conventional catalysts. The basic concept for the catalyst design including the background and our recent successful examples for precise synthesis of new polymers will be introduced in the seminar.
