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

Abstract

There are provided a process for producing a catalyst for α-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 α-olefin polymer, which comprises the step of homopolymerizing or copolymerizing an α-olefin in the presence of a catalyst for α-olefin polymerization produced by the above process.

Dependencies are inferred from the claim text.
