Abstract
A solid catalyst component for the (co)polymerization of olefins CH2═CHR, in which R is a hydrocarbyl radical with 1-12 carbon atoms, optionally in mixture with ethylene, comprising Ti, Mg, Cu, Cl, and an electron donor compound characterized by the fact that the Cu/Ti weight ratio is lower than 0.5.

A solid catalyst component for the (co)polymerization of olefins CH2═CHR, wherein R is a hydrocarbyl radical with 1-12 carbon atoms, with optional ethylene, comprising Ti, Mg, Cu, Cl, and an electron donor compound wherein the Cu/Ti weight ratio is lower than 0.5, the amount of Cu is lower than 2% by weight based on the total weight of the solid catalyst component, and when the Cu atoms are derived from CuCl2, the electron donor is selected from alkyl and aryl esters of substituted aromatic mono- or polycarboxylic acids, and the amount of Ti ranges from 1.1-2.5% of the total weight of the solid catalyst component.
