<P>PROBLEM TO BE SOLVED: To provide a both-terminals-functional polyolefin useful in various uses. <P>SOLUTION: This method for producing both-terminals-functional polyolefin obtained by performing the following process 1, process 2 and process 1 in this order in the presence of an olefin polymerization catalyst containing (A) the Grups 4 to 5 transition metal-containing compound, and then performing the process 3 as necessary and having a 1.0 to 1.5 molecular weight distribution (Mw/Mn) obtained by gel permeation chromatography (GPC) is provided. [Process 1] The process of contact-mixing (C) a polar group-containing olefin. [Process 2] The process of catalytically mixing ethylene and (D) at least 1 kind olefin selected from 3-20C olefins by n-times (wherein, (n) is an integer of ≥1). Provided that, when the (n) is an integer of ≥2, the kind or composition of the olefin (D) used in each of the times is different. [Process 3] The chemical conversion process. <P>COPYRIGHT: (C)2009,JPO&INPIT |
