Abstract

A catalyst component for the (co)polymerization of olefins is provided. The catalyst comprises titanium, magnesium halogen and a mixed electron-donor and a catalyst for the (co)polymerization of olefins comprising:(A) the catalyst component; (B) an organic aluminum compound; and (C) an organic silicon compound. A polymer with high and adjustable stereospecificity and broad molecular weight distribution can be prepared by using the catalyst.
