Abstract: PURPOSE: A segmented copolymer and a carbon nano tube containing the same are provided to avoid defects in a carbon nanotube structure through an aromatic hydrocarbon group when applied to the carbon nanotube, and to improve dispersibility of the carbon nanotube. CONSTITUTION: A segmented copolymer comprises a first polymer segment consisting of a structure unit based on a maleic anhydride-vinyl group and a second polymer segment consisting of a structure unit based on a vinyl group. The segmented copolymer is represented by chemical formula 1, wherein R1 is and alkyl group substituted with a polycyclic aromatic hydrocarbon group; R2 and R3 are independently substituted or unsubstituted aromatic hydrocarbon group; m is 1-50, n is 0-50, p is 1-500, and q is 10-750.
