Abstract

Abstract: An anionic complex 〔Li(DME)₃〕〔(η⁵－MeCp)Nd(t－Bu)₃〕 was obtained by the reaction of MeCpNdCl₂.2LiCl·nTHF with 2 mols of t-BuLi in the mixed soIution of THF and pentane. The complex was characterized by elemental analysis and IR spectroscopy. The complex is soluble in styrene and able to catalyze its polymerization in bulk to give an atactic polystyrene.

Key words: cyclopentadienyl rare earth complex, synthesis, styrene, catalytic polymerization
