Fine Tuning of Catalyst Active Sites to Access Advanced Ultrahigh-Melting Polyolefins.
Polyolefins with melting temperatures above 200°C are rare, as their synthesis typically relies on the polymerization of highly sterically congested α-olefins, which is challenging for both industrial Ziegler-Natta and homogeneous catalysts. Pyridylamido-Hf complexes are molecular catalysts known for their high activit...
