摘要： The present invention relates to a method for preparing an olefin-based polymer, comprising a step of polymerizing an olefin-based monomer in the presence of a catalytic composition comprising cis-isomers and trans-isomers of a transition metal compound. According to the method for preparing the olefin-based polymer in accordance with one embodiment of the present invention, it is possible to obtain a similar level of density and molecular weight compared to a conventional polymer by using a relatively lower amount of octene, compared to the amount of octene used in conventional polymer preparation, and thus it is possible to prepare an olefin-based polymer which has a more excellent copolymerization property and is more stable.
