| Abstract: | Polymerization of acrylonitrile was carried out using, for the first time, the lanthanide-sodium alkoxide clusters Ln2(OCH2CH2NMe2)12(OH)2Na8 Ln=Yb (1), Nd (2) and Sm (3)] as single component catalysts. These heterobimetallic complexes exhibit high activity and give atactic polyacrylonitriles
with high molecular weight. The polymerization temperature can be varied over the range −78 to 50°C. The solvent has a substantial
effect on the polymerization activity. The order of activity for solvents is DMF>DME≈toluene≈THF>hexane. |
