    摘要: A pre-polymerized catalyst component for the polymerization of olefins CH2═CHR, wherein R is hydrogen or a C1-C12 hydrocarbon group, characterized by comprising a non-stereospecific solid catalyst component, comprising Ti, Mg and a halogen, said pre-polymerized catalyst component containing an amount of a (co)polymer of a monomer having formula CH2═CHA, where A is a C6 aliphatic or aromatic ring, optionally substituted, up to 5 g per g of said solid catalyst component. Said prepolymerized catalyst shows an excellent balance in terms of activity, morphological stability, reduced tendency to agglomeration and hydrogen response.
