preparation example Construction
[0095] The invention relates to a preparation method of a supported non-metallocene catalyst, comprising the following steps: reacting a magnesium compound optionally in the presence of alcohol with a chemical treatment agent selected from group IVB metal compounds in a solvent to obtain the first slurry steps; contacting the non-metallocene complex with the first slurry to obtain a second slurry; and directly drying the second slurry to obtain the supported non-metallocene catalyst.
[0096] The magnesium compound will be specifically described below.
[0097] According to the present invention, the term "magnesium compound" refers to an organic or inorganic solid anhydrous magnesium-containing compound conventionally used as a carrier of a supported olefin polymerization catalyst using a common concept in the art.
[0098] According to the present invention, examples of the magnesium compound include magnesium halides, alkoxymagnesium halides, alkoxymagnesiums, alkylmagnesiu...
Embodiment 1
[0272] The magnesium compound adopts anhydrous magnesium chloride, the solvent adopts toluene, the alcohol adopts butanol, the chemical treatment agent of IVB group metal compound adopts titanium tetrachloride, and the non-metallocene complex adopts the structure compound of.
[0273] Weigh 5g of anhydrous magnesium chloride, add solvent and alcohol, dissolve completely at room temperature, then add chemical treatment agent dropwise at a uniform speed for 1 hour, stir and react at 60°C for 4 hours to obtain the first slurry, and then add the non-metallocene complex to the second The first slurry was stirred and reacted at room temperature for 6 hours to obtain a second slurry, and finally vacuum-dried at room temperature to obtain a supported non-metallocene catalyst.
[0274] The proportioning ratio is as follows: the ratio of magnesium compound to solvent is 1mol: 210ml; the molar ratio of magnesium compound to alcohol is 1:0.5; the molar ratio of magnesium compound to non-...
Embodiment 2
[0277] Basically the same as Example 1, but with the following changes:
[0278] The alcohol adopts ethanol, the solvent is changed to ethylbenzene, and the chemical treatment agent of IVB group metal compound is changed to zirconium tetrachloride (ZrCl 4 ), the non-metallocene complex adopts
[0279] Wherein the ratio is as follows: the ratio of magnesium compound to solvent is 1mol: 150ml; the molar ratio of magnesium compound to alcohol is 1: 1.64; the molar ratio of magnesium compound to non-metallocene complex is 1: 0.15; The calculated chemical treatment agent molar ratio is 1:0.20.
[0280] Supported non-metallocene catalysts are designated CAT-2.
