Abstract

The highly cis-1,4 functionalized polyconjugated dienes was prepared by high-position/stereoregular coordination polymerization of polyconjugated dienes can effectively introduce a number of heteroatom groups into synthetic rubbers, but it cannot only effectively improve the performance of synthetic rubber, but also develop new functional polyconjugated diene materials to broaden its application range. However, the rare earth metal catalysts that can promote the coordination polymerization of polar conjugated diene monomers are currently very limited. The bipyridine complex ((C₂₀H₃₀N₂)Sc(CH₂SiMe₃)₃(THF)) was simply synthesized using bipyridyl derivative ligand and equal amounts of Sc(CH₂SiMe₃)₃(THF)₂. For the bipyridyl-scandium trialkyl complex, different feeding ratios of cocatalyst borate can produce different catalytically active species. These generated catalytically active species can achieve coordination polymerization of polar 2-(2-methoxyphenyl)-1,3-butadiene.
