METALLOCENE CATALYSTS, THEIR SYNTHESIS AND THEIR APPLICATION FOR OLEFIN POLYMERISATION Russian patent published in 2009 - IPC C08F10/00 C08F2/18 C08F4/642 

FIELD: chemistry.

SUBSTANCE: highly efficient catalytic systems on carrier include metallocene(s) and cocatalyst(s), such as alumoxane(s), which preferably can be applied for olefin polymerisation, and to economical method of obtaining similar catalytic systems, to method of application of similar catalytic systems for olefin polymerisation and copolymerisation and to polymers, obtained using similar catalytic systems. Described are methods of obtaining catalytic system (versions), which include stages: 1) joining material of carrier with first composition, which includes at least one alumoxane in first solvent; 2) heating of joined carrier material at least with one alumoxane in first solvent to temperature in range at least from 30°C to approximately 200°C, obtaining carrier, containing alumoxane; 3) contacting of carrier material, alumoxane, with second composition, which includes at least one metallocene compound, second solvent and cocatalyst, cocatalyst includes second portion at least of one alumoxane either individually, or in combination with ionic compound and/or Lewis acid. Described is method of olefin polymerisation including: a) preparation of catalytic system; b) contacting of one or several olefins, each of which contains from 2 to approximately 20 carbon atoms, in polymerisation reaction conditions with catalytic system.

EFFECT: obtaining catalytic systems on carrier, which possess improved properties in process of carrying out polymerisation at polymerisation temperatures from 50 to 100°C used in industry.
