Abstract

The present disclosure relates to a solid catalyst component for the (co)polymerization of olefins CH2═CHR, in which R is hydrogen or a hydrocarbyl radical with 1-12 carbon atoms, comprising Ti, Mg, and Cl, and optionally an electron donor compound selected from the group consisting of ethers, amines, silanes, carbamates ketones, esters of aliphatic acids, alkyl and aryl esters of optionally substituted aromatic polycarboxylic acids, diol derivatives chosen among monoesters monocarbamates and monoesters monocarbonates or mixtures thereof, comprising from 0.1 to 50% wt of Bi with respect to the total weight of the solid catalyst component.
