FIELD: chemical technology, catalysts. SUBSTANCE: new chrome-containing compounds, for example, chrome pyrrolides were produced by forming chrome salt mixture, metal amide and electron-donor solvent, for example, ether. These new chrome-containing compounds or chrome pyrrolide can be used without applying or as applied on inorganic oxide backing for trimerization and/or polymerization of olefins. EFFECT: improved method of producing. 41 cl, 22 tbl |
