Control of Chain Transfer by Tailored Metal–Phenyl π ‐Interactions in Bis(Imino)Pyridyl Cobalt‐Catalyzed Ethylene Polymerization

Open DOI

Heng Gao, Chong Wang, Xieyi Xiao et al.

In bis(imino)pyridyl iron/cobalt‐catalyzed ethylene polymerization, broad and bimodal molecular weight distributions of polyethylenes (PEs) are often produced because of two different chain transfer pathways. In this paper, a combined th...
