Abstract
The present invention relates to a method of preparing an olefin-based polymer including a step of polymerizing an olefin monomer in the presence of a catalyst composition including a cis isomer and a trans isomer. According to the method of preparing an olefin-based polymer according to an embodiment of the present invention, similar level of density and molecular weight may be exhibited with a relatively smaller amount of octene when compared to that of a common polymer. Thus, a stable olefin-based polymer having good copolymerization properties may be prepared.
