| Research Abstract |
We used the palladium catalyst having non- or low-symmetrical structures for polymerization of olefins, dienes, and trienes. Cyclopolymerization of terminal dienes and bis-terminal trienes were promoted by the complexes and yielded the polymers having cyclic structures along the polymers in a regulated form. The stereochemistry of the polymerization is influenced by the structures of the catalysts, and low-symmetrical structure catalyst also provided the regulated polymers. We examined synthesis of the dipalladium complexes supported by a macrocyclic ligand and their use as the polymerization of several monomers. Although the cyclopolymerization of diene was not well catalyzed by the complexes, polymerization of olefins and copolymerization of olefins with polar monomers resulted in new polymer synthetic reactions. The copolymerization afforded elastomeric polymer materials with high Young's modulus.
