Electron donor composition for a solid catalyst, solid catalyst composition used in the polymerisation of alpha-olefins, and process for the production of a polymer consisting of alpha-olefin units using the solid catalyst composition

摘要

The present invention relates to an electron donor composition comprising a dihydroanthracene derivative and a phthalate ester. Furthermore, the present invention relates to a solid catalyst composition comprising the electron donor composition for use in α-olefin polymerisation. The present invention further relates to the process for the production of a polymer containing α-olefin monomer units.
