In the process for preparing an olefin polymer, an olefin of 2 to 20 carbon atoms is polymerized in the presence of an olefin polymerization catalyst comprising a transition metal compound represented by, for example, the following formula (I): LmMXn (I) wherein M is a transition metal atom of Group 3 to Group 11 of the periodic table, m is 1 to 5, n is a number satisfying a valence of M, L is a ligand coordinated to the central metal M and is a ligand containing a heteroatom having no direct bond to the central metal, and X is a halogen atom, a hydrocarbon group or the like.
