Abstract

A solid catalyst component comprising Ti, Mg, halogen and a couple of monofunctional electron donor compounds MD1 and MD2 selected from esters and ethers, said donors being present in amounts such that the molar ratio MD1/MD2 ranges from 20 to 800. The so obtained catalyst component when converted into a catalyst is able to produce ethylene polymers with good morphological properties even under drastic polymerization conditions.
