摘要：
The invention relates to a granular catalyst component for polymerizing olefins, its usage in the polymerization of olefins and a method for its preparation. A granular catalyst component for polymerization catalysts of olefins, which contain one or more catalytically active transition metal compounds belonging to the groups IV-VIII of the periodic system and combined with a carrier as well as optionally one or more compounds acting as a medium or an electron donor. The catalyst component is formed by layers of particles containing the constituents of the catalyst component essentially smaller than the desired granular size by repeatedly layering on top of the particles a solution or a suspension containing the constituents of said catalyst component, until the desired granular size is obtained.
