<p>[Problem] To efficiently obtain anα-olefin polymer having a high melting point and a high molecular weight. [Solution to Problem] The process for preparing an olefin polymer of the present invention is a process for preparing an olefin polymer, comprising polymerizing at least one monomer selected fromα-olefins of 2 or more carbon atoms, wherein the polymerization is carried out at a temperature of not lower than 40° C. in the presence of a catalyst comprising a transition metal compound component (A) which comprises two or more kinds of transition metal compounds (a) represented by the following formula [A1] and an organometallic compound component (B) which comprises an organometallic compound (b), propylene is contained in the monomer, and the olefin polymer is an olefin polymer whose weight-average molecular weight (Mw) and number-average molecular weight (Mn), as determined by gel permeation chromatography (GPC), satisfy the relationship of 1≰(Mw/Mn)≰3, and which has a melting point (Tm), as determined by DSC, of not lower than 150° C. and an intrinsic viscosity ([η]) of not less than 1.5 dl/g.</p> |
