METHOD OF PRODUCING CATALYTIC COMPOSITIONS AND POLYMERIC PRODUCTS PRODUCED WITH USING THESE CATALYTIC COMPOSITIONS Russian patent published in 2017 - IPC C08F4/65 C08F110/02 C08F10/02 

FIELD: chemistry.

SUBSTANCE: method consists of: combining one or more carriers with one or more magnesium-containing compounds under the reaction conditions to produce the first reacted product; a compound of one or more chlorinating compounds selected from the group consisting of one or more chlorinated silanes including dimethyldichlorosilane, chlorotrimethylsilane, methyltrichlorosilane, diethyl dichlorosilane, tert-butyldimethylsilyl chloride, n-butyltrichlorosilane, or any combination thereof with the first reacted product under the reaction conditions to produce the second reacted product and the compounds of one or more titanium-containing compounds selected from the group consisting of one or more titanium alkoxides, one or more titanium halides and combinations thereof with the second reacted product under the reaction conditions to produce a catalyst. Moreover, the catalyst essentially does not contain donor compounds. A method of producing polyethylene and polyethylene are also provided.

EFFECT: invention makes it possible to produce polyethylene having a significantly increased molecular weight distribution.
