POLYACRYLONITRILE POLYMER-MODIFIED CARBON NANOTUBE, METHOD FOR PRODUCING THE SAME, POLYACRYLONITRILE-MODIFIED CARBON NANOTUBE COMPOSITE, POLYACRYLONITRILE FIBER BUNDLE, AND METHOD FOR PRODUCING CARBON FIBER

摘要

PROBLEM TO BE SOLVED: To provide a carbon nanotube which includes a grafted polyacrylonitrile polymer and is excellent in dispersibility to polyacrylonitrile.

SOLUTION: The polyacrylonitrile-modified carbon nanotube includes a polyacrylonitrile polymer (A) graft-polymerized to a carbon nanotube. The ratio of the polyacrylonitrile polymer component in the polyacrylonitrile-modified carbon nanotube is 25-99 mass%, and the number average molecular weight of the polyacrylonitrile polymer moiety is 3,000-100,000 g/mol.
