these catalysts enabled the copolymerization of ethylene with a broad scope of commercially available polar comonomers such as acrylates
acrylic acid

and long-chain 6-chloro-1-hexene to give functionalized polyethylene with reasonable catalytic activities (up to 10

) and incorporations (up to 5.3 mol%). This contribution suggests that
besides the modulation of conventionally steric and electronic factors
the connectivity (at different linking positions) of BPMO (P
O) donors to the heteroaryl backbone also greatly influences the catalyst properties in terms of catalytic activity
polymer branching content
comonomer scope
and comonomer incorporation.
