CATALYST COMPONENTS FOR THE POLYMERIZATION OF OLEFINS |
摘要 |
Prepolymerized catalyst component for the polymerization of olefins CH2═CHR in which R is hydrogen or a hydrocarbyl radical with 1-12 carbon atoms, having average particle size equal to or lower than 30 μm comprising a solid catalyst component comprising magnesium halide, a titanium compound having at least a Ti-halogen bond and at least two electron donor compounds one of which being selected from 1,3-diethers and the other one being selected from esters of aromatic mono or dicarboxylic acids, said solid catalyst component being prepolymerized with an olefin, having from 2 to 10 carbon atoms, to such an extent that the amount of the olefin prepolymer is equal to or lower than 50 g per g of solid catalyst component. |
