摘要：
Processes of polymerizing olefin monomers. The process includes reacting ethylene and optionally one or more olefin monomers in the presence of a catalyst system, wherein the catalyst system comprises: modified-hydrocarbyl methylaluminoxane having less than 50 mole percent AlRA1RB1RC1 based on the total moles of aluminum, where RA1, RB1, and RC1 are independently is linear (C1-C40)alkyl, branched (C1-C40)alkyl, or (C6-C40)aryl; and one or more metal-ligand complexes according to formula (I).
