FIELD: catalysts, chemical technology.
SUBSTANCE: invention elates to catalytic compositions, methods for preparing such compositions, and to methods for preparing polymers based on thereof. Invention describes a composition of a spraying drying catalyst precursor and a method for preparing a spraying drying catalyst precursor wherein this composition comprises inert filling agent, magnesium, transient metal, solvent and one electron-donor compound. The composition of catalyst precursor doesn't contain practically other electron-donor compounds and the molar ratio of electron-donor compound to magnesium = 1.9 or less, and the composition comprises particles with particles size from about 10 mcm to about 200 mcm. Also, invention describes catalysts prepared from spraying drying catalyst precursors, and methods for polymerization using such catalysts. Invention provides the improved output and catalytic activity of catalyst.
EFFECT: improved properties of catalyst, improved method of polymerization.
