Examples
Embodiment 1
[0145] (Example 1 and Comparative Example 1) Processed product in heptane
[0146] The complex described in Table 1 was stirred in 50 ml of heptane for 2 hours to produce an aluminum phenoxide compound. A part of the obtained compound was decompressed at 80° C. to remove the heptane, and the obtained solid was passed 1 H-NMR confirmed the presence or absence of active hydrogen atoms. In addition, confirmation of the presence or absence of residual active hydrogen atoms was carried out with 5.1 to 5.5 ppm as the peak assigned to N-H and 5.0 to 5.1 ppm as the peak assigned to O-H. These results are shown in Table 1.

Embodiment 2 and comparative example 2
[0149] (Example 2 and Comparative Example 2) Processed product in mineral oil
[0150] The complex described in Table 2 was stirred in 50 ml of mineral oil for 2 hours to produce an aluminum phenoxide compound. A part of the obtained compound was depressurized at 80° C. to remove the mineral oil, and it was confirmed in the same manner as in Example 1 whether or not active hydrogen atoms remained in the obtained solid. These results are shown in Table 2.

[0153] (Example 3 and Comparative Example 3) Solvent-free treated product
[0154] Under an argon atmosphere, the complexes described in Table 3 were mixed with a mixer for 2 hours to produce an aluminum phenoxide compound. In the same manner as in Example 1, it was checked whether or not active hydrogen atoms remained in the obtained compound.
[0155] The results are shown in Table 3.

Embodiment 4
[0162] (embodiment 4, comparative example 5 and reference example 1) adding in the polymerization system
[0163] 1. Preparation of solid Ti catalyst
[0164] Anhydrous magnesium chloride 4.76g (50mmol), decane 25ml and 2-ethylhexanol 23.4ml (150mmol) were heated and reacted at 130°C for 2 hours to form a uniform solution, and phthalic anhydride was added to the solution 1.11 g (7.5 mmol), and the reaction was further stirred at 130° C. for 1 hour to dissolve phthalic anhydride in the homogeneous solution. After cooling the homogeneous solution thus obtained to room temperature, the whole was added dropwise to 200 ml (1.8 mol) of titanium tetrachloride kept at -20°C over 1 hour. After the dropwise addition, the temperature of the mixture was raised to 110° C. over 4 hours, and when it reached 110° C., 2.68 ml (12.5 mmol) of diisobutyl phthalate was added, and then stirred at the same temperature for 2 hours and kept . After the 2-hour reaction, the solid part was collected ...
