Abstract
To provide a process for producing an olefin polymer, which makes it possible to use, as a solvent for use in the catalyst preparation and the like, an aliphatic hydrocarbon solvent instead of an aromatic hydrocarbon solvent causing large environmental burden, and which has good olefin polymerization activity. A process for producing an olefin polymer, characterized by having a step comprising feeding an olefin polymerization catalyst solution, which is obtained by mixing a metallocene compound, a compound that reacts with the metallocene compound to form an ion pair and at least one compound selected from an organoaluminum compound and an organoaluminum oxy compound with a saturated hydrocarbon solvent, to a polymerization reactor and solution-polymerizing an olefin in the polymerization reactor.
