Document Type and Number:
Japanese Patent JP2010280894
Kind Code:
A
Abstract:

To provide a catalyst for polymerization of olefins giving a homogenous comonomer distribution, high polymerization activity, and desirably, applications to gas phase polymerization.

The catalyst component for olefin (co)polymerization, in particular for producing LLDPE, comprises Mg, Ti, halogen, and an electron donor compound (ED) belonging to ethers, esters, amines, ketones, or nitriles, and has the molar ratio of Mg/Ti higher than 5 and the molar ratio of ED/Ti higher than 3.5. The catalyst component displays a homogeneous distribution of the comonomer in and among the copolymer chains.
