a General conditions:pre-cat.:L-Fe(acac)3,[Fe]=2μmol;[Al]/[Fe]=2000;solvent:toluene,50 mL;T=50°C;P=0.1 MPa;t=30 min;b The mass fraction of insoluble polymers in the total products;c Total activity:kg/ (mol Fe·h)

Besides the utilization of PhOHs as the[―OH]source in thefirst step of reaction with AlMe3,two other types of[―OH]2-naphthol and cyclohexanol,were also explored for th preparation of aluminoxane activators.The preparatio conditions were identical to the aforementioned ones with th[H2O]/[Al]ratio used in the hydrolysis procedure to be 0.7The results are summarized in Table 3.
