Abstract: PURPOSE: A manufacturing method of polyacrylonitrile-based polymer is provided to manufacture polyacrylonitrile-based polymer with high yield by only short polymerization reaction time and to be able to be melt-spinning because of high crystallinity. CONSTITUTION: A manufacturing method of polyacrylonitrile-based polymer comprises a step of irradiating a composition comprising an acrylonitrile monomer with microwave to polymerization. A manufacturing method of polyacrylonitrile-based carbon fiber comprises a step of manufacturing polyacrylonitrile-based polymer by irradiating a composition comprising an acrylonitrile monomer with microwave; a step of manufacture precursor fiber by melt-spinning the polyacrylonitrile-based polymer; and a step of stabilizing and carbonizing the precursor fiber.
