Abstract

A study was conducted to demonstrate in situ diversification of (pyridylamide)hafnium(IV) catalysts. An extensive density functional theory (DFT) study was conducted for several C 1-symmetric and C s-symmetric precatalysts to investigate the diversification of the (pyridylamide)hafnium(IV) catalysts. The study also investigated propylene polymerizations were investigated with two catalysts to find evidence of multisite behavior. It was observed that catalyst systems 1/Ph 3C][B-(C 6F 5) 4] and 2/Ph 3C][B(C 6F 5) 4] produced polypropylene samples with broad molecular weight distributions.
