摘要

The tetrameric neodymium-silsesquioxane cage complex

{[(i-C4H9)7(Si7O12)Nd]4NaCl}

was prepared and used as precursor for the polymerization of isoprene. When activated by AlEt3 in the presence of TMSCl

this POSS-Nd complex (POSS = polyhedral oligomeric silsesquioxane) shows a moderate activity for the polymerization

and the effects of different ratios of Al/Nd

Cl/Nd and time on the polymerization were investigated. Moreover

The POSS-Nd complex may serve as models for the silica-supported rare earth catalyst

and a simplified surface model was also proposed.
