Abstract:

Disclosed are catalyst systems, processes for making the catalyst systems, and processes for polymerizing at least one olefin monomer comprising ethylene to form a low-density polyethylene (LDPE). The polymerization process uses a catalyst system that can include: at least one diimine complex having the formula I:wherein M is Ni, Pd, or Pt;
