<p>PROBLEM TO BE SOLVED: To provide a highly-branched polymer used as a carbon nano-tube dispersant which dissolves carbon nano-tube in a medium, e.g. an organic solvent, in a state of being isolated to the single size.SOLUTION: A highly-branched polymer is of formula (15). Since the highly-branched polymer has an excellent capacity of dissolving carbon nano-tube, a composition containing carbon nano-tube in an isolated and dissolved state can be obtained by using the polymer as a dispersant.</p> |
