Fine Tuning of Catalyst Active Sites to Access Advanced Ultrahigh‐Melting Polyolefins
Angewandte Chemie, EarlyView.A redesign of the active site of the pyridylamido hafnium (Hf) catalysts can enhance the performance of this catalyst family and unlock previously inaccessible polymer structures. When the catalyst is precontacted with allyltrimethylsilane the active species is modified and the catalyst experiences a new life becoming able to polymerize sterically ...
