Abstract
Allylic complexes of lanthanides bearing a fluorenyl-based ligand are active single-component catalysts for the polymerization of styrene, giving highly syndiotactic polymers (rrrr > 99%) with low to high molecular weight (Mn = 8000−135 000) and narrow polydispersities (Mw/Mn = 1.25−2.1).Keywords
