FIELD: chemistry.

SUBSTANCE: present invention relates to a solid catalyst component for (co)polymerizing olefins CH₂=CHR, in which R is hydrogen or a hydrocarbon radical having from 1 to 12 carbon atoms containing Ti, Mg, Cl and an electron donor compound selected from the group consisting of alkyl and aryl esters of optionally substituted aromatic polybasic carboxylic acids, esters of malonic acids, glutaric acid esters, maleic acid esters, succinic acid esters, derivatives of diols selected from dicarbamates, monoesters of monocarbamates and monoesters of monocarbons and 1,3-diethers of formula , where R, R^I, R^II, R^III, R^IV and R^V are equal or different from one another and are hydrogen or hydrocarbon radicals having from 1 to 18 carbon atoms, when R^VI and R^VII are equal or different from each other and have the same value of R–R^V, except that they can not be hydrogen, and one or more groups R–R^VII may be linked to form a cycle, or mixture thereof, characterized in that it contains an amount of Bi halide in the range of 1 to 20 % by weight. Method and adduct of formula MgCl₂•pROH to produce said solid catalyst component, and a catalyst for the (co)polymerization of olefins CH₂=CHR containing such a solid catalyst component, and a process for (co)polymerizing olefins CH₂=CHR using such a catalyst are also described.

EFFECT: increase in activity and/or stereospecificity in the polymerization of olefins, for example ethylene or propylene.
