Process for producing catalyst for alpha -olefin polymerization and process for producing alpha -olefin polymer

摘要

There are provided a process for producing a catalyst for alpha-olefin polymerization, which comprises the step of contacting (1) a solid catalyst component having Ti, Mg and a halogen as essential components, (2) an organoaluminum compound and (3) a compound having a -C-O-C-O-C- bond group in a closed ring structure with one another; and a process for producing an alpha-olefin polymer, which comprises the step of homopolymerizing or copolymerizing an alpha-olefin in the presence of a catalyst for alpha-olefin polymerization produced by the above process.
