Abstract
The present disclosure relates to a porous solid adduct comprising magnesium chloride and ethanol, characterized by a relationship between the content of alcohol, average pore radius and amount of porosity deriving from pores with radii of 100-1000 nm, and catalyst components produced therefrom that are capable of producing polyolefins with increased porosity.
