PRODUCTION OF SPINNING PITCH FOR CARBON FIBER

PURPOSE:To produce spinning pitch having excellent spinnability and giving a carbon fiber having high strength and elastic modulus, by flowing down molten pitch containing meso-phase through a small hole into an evacuated space, thereby removing low-boiling component. CONSTITUTION:Pitch containing m...
