    专利说明:

    The invention relates to the plastics industry and can be used to obtain polyethylene.
    The purpose of the invention is to increase the catalyst activity.
    Example 1 Preparation, catalyst,
    419 mg of chromium acetylacetonate (il (1.2 mol) is suspended in dry low-boiling gasoline (boiling-out interval 65-85 ° C) in a one-liter flask equipped with a stirrer, reflux condenser and inlet tube. The suspension with stirring is heated to the boiling point of gasoline and 712 mg (3.59 mmol) of triisobut: nlalu: iini (CHIBA) is added to it in the feces. The resulting dark brownish-green solution contains only traces of solid materials.
    After filtering, this solution is added dropwise to 60 g of Aeros1-sha suspension in 900 ml of dry gasoline. Before suspending, the aerosil is pre-dried, namely, it is heated for 16 hours at. In a short time, the solution becomes colorless, and its color changes to silica gel carrier. After this, silicon dioxide with precipitated chromium on it is separated from the solvent 5 by distillation of light gasoline, and the powder obtained after this is kept for 16 h under vacuum.



    at 5 ° C) ° C. Thereafter, the port roadblock is watered in a stream of dry air at 900 ° C in a rotary kiln. Heating takes 1 hour, after which the powder is kept at 900 ° C for another 1 hour. Then the catalyst powder is cooled and suspended in gasoline, and the amount of gasoline is taken such that the suspension contains 5 g of supported catalyst per 100 ml of gasoline. As a result of the analysis of the calcined catalyst powder, it is found that it contains 0.12% by weight of chromium and 0.20% by weight of aluminum,
    Polymerization of ethyl. 40 ml of catalysts suspension are added to 1500 ml of dry gasoline, placed in a 3.2 l autoclave with a stirrer. Then, 0.6 ml of 1 M solution of TIBA 3 gasoline is added to the reactor, after which the reactor is closed and the pressure in it is pressurized with ethylene feed containing 5% hydrogen. The autoclave is heated to 85 ° C. and its contents are polymerized for i h at a total pressure of A atm. The yield of polyethylene is 128 g, which corresponds to a catalyst activity of 1297 g of polyethylene per mmol of chromium atm. ethylene per hour Melt flow index (MFI) according to А5ТМД- 238 is equal to 0.33.
    Examples 2-20. The process is carried out analogously to Example 1. The conditions and results of the process are given in tab.
