CATALYST SYSTEMS AND METHODS FOR USE THEREOF TO PRODUCE POLYOLEFIN PRODUCTS Russian patent published in 2015 - IPC C08F4/642 C08F10/02 C08F4/02 

FIELD: chemistry.

SUBSTANCE: invention relates to catalyst systems for producing polyolefins and methods for production thereof. The catalyst system includes a catalytically active compound with one type of active centres, a support which includes fluorinated aluminium oxide and aluminoxane. Content of the aluminoxane ranges from 8 mmol to 0.1 mmol per gram of the support.

EFFECT: use of a fluorinated support which contains aluminium oxide enables to achieve high catalyst efficiency owing to a higher concentration of the transition metal-based component in the catalytically active compound with one type of active centres.
