Catalytic components for olefin polymerization. The present invention describes catalytic components for ethylene polymerization comprising Ti, Mg, halogen, OR 'groups, where R' is a C1-C12 hydrocarbon group optionally containing heteroatoms, having a specific relationship between OR '/ Ti molar ratios. and MgITi and characterized by a specific SS-NMR standard, and which are particularly useful for preparing narrow MWD crystalline ethylene polymers. |
