High-Temperature Solution-Phase Ethylene (Co)polymerization Catalyzed by a [O<sup>–</sup>N<sup>–</sup>P]TiBn<sub>2</sub> Complex
The development of thermally robust olefin polymerization catalysts with high activity for high-temperature solution-phase polymerization processes represents a pivotal research domain in polymer chemistry, but it remains a challenge. In this work, we present a structurally well-defined prealkylated complex, [O–N–P]TiBn2, to catalyze high-temperature solution-phase ethylene (co)polymerization. Using modified methyl aluminoxane as an activator, the Ti complex achieved moderate ethylene/1-octene copolymerization activity (2.3 × 105 g polymer/(mol Ti·h·atm)) at 150 °C with 16.4 mol % 1-octene incorporation.
