Embodiment 1
[0032] Preparation of spherical carrier containing 9,9-bis(methoxymethyl)fluorene
[0033] Under nitrogen protection, 95.2 g of anhydrous magnesium chloride, 190.40 ml of absolute ethanol (alcohol / magnesium molar ratio of 3.24) and 240 ml of white oil were added to the reactor. Heat up to 127°C and stir until MgCl 2 After all dissolved, add 179.4 mmol 9,9-bis(methoxymethyl)fluorene, continue stirring for 2 hours, stop the reaction to obtain a homogeneous solution of magnesium chloride alcoholate containing 9,9-bis(methoxymethyl)fluorene .
[0034] Under nitrogen protection, 1000 ml of white oil and 100 ml of silicone oil preheated to 127°C were added to the reactor and mixed with the homogeneous solution of magnesium chloride alcoholate containing 9,9-bis(methoxymethyl)fluorene, and Stir for 30 minutes at 500-800 rpm. The contents of the reactor were then transferred through an emulsifier to 5 liters (stirred) of hexane pre-cooled to -25 to -35°C under nitrogen pressure. T...
Embodiment 2-3
[0047] The spherical solid catalyst component was prepared by using the carrier (B) and the carrier (C), other conditions were the same as those in Example 1, and the polymerization results were listed in Table 2.
[0048] implement
[0049] EB is ethyl benzoate; diether is 9,9-(methoxymethyl)fluorene.
Embodiment 4-6
