## Abstract Novel bridged dinuclear diimine nickel and palladium complexes catalyzed the vinyl addition polymerization of norbornene at a single active site with high activity. The latter exhibited higher activity than the former. Smaller substituents around the imido group in the ligand were more
The copolymerization of styrene (St) with a styrene-terminated polyisoprene macromonomer (SIPM) by a nickel(II) acetylacetonate [Ni(acac) 2 ] catalyst in combination with methylaluminoxane (MAO) was investigated. A SIPM with a high terminal degree of functionalization and a narrow molecular weight d
Copolymerization of styrene (St) and butadiene (Bd) with nickel(II) acetylacetonate [Ni(acac) 2 ]-methylaluminoxane (MAO) catalyst was investigated. Among the metal acetylacetonates [Mt(acac) x ] examined, Ni(acac) 2 showed a high activity for the copolymerization of St and Bd giving copolymers havi
