| 摘要 |
The present invention relates to catalysts component for the polymerization of ethylene and its mixtures with olefins CH2-CHR, wherein R is an alkyl, cycloalkyl or aryl radical having 1-12 carbon atoms, comprising Ti, Mg, halogen, and 1,2-dimethoxyethane as internal electron donor compound. The catalyst of the invention is suitably used in (co)polymerization processes of ethylene to prepare (co)polymers having narrow Molecular Weight Distribution (MWD) and high bulk density.
