  摘要：

  An olefin polymerization process is carried out in the presence of a catalyst system comprising a pre-polymerization catalyst, a boron-based catalyst activator, an alkylaluminoxane co-catalyst, and a hindered phenol compound. The pre-polymerization catalyst is a titanium complex and has an indenoindolyl ligand bridged to a phenoxy ligand via a silyl group. The catalyst system is effective at polymerizing ethylene with alpha-olefins in a solution phase polymerization process at high temperatures and produces ethylene copolymers with high molecular weight and high degrees of alpha-olefin incorporation.
