<p>A branched polyolefin having various excellent properties; a process for producing the branched polyolefin; and a thermoplastic resin composition containing the branched polyolefin. The branched polyolefin is made up of olefin chains (A) and olefin chains (B) which each comprises repeating units derived from an olefin as the main structural units, the chains (B) being bonded to the chains (A) at sites other than the ends of the chains (A) through bonds each having a carbonyl group and the number of the chains (B) being 1 or larger per chain (A). The process for producing a branched polyolefin comprises reacting a functional polyolefin (C) having a carboxyl and/or acid anhydride group bonded to each end thereof and further having one or more carboxyl and/or acid anhydride groups bonded to other sites with a terminal-modified polyolefin (D) having only at an end thereof a group reactive with a carboxyl or acid anhydride group.</p> |
