    摘要: In the production of carbon fibers wherein a carbon-containing fiber-forming material is spun as a solution, the spun-filaments are converted to solid fibrous material, and the fibrous material is carbonized, the improvement which comprises including in said solution at least one fiber-forming high polymer at a concentration of about 0.001 to 10 percent by weight and a greater amount of a carbon source comprising at least one carboncontaining organic material having a softening or melting point in excess of about 80* C., whereby the solution of said carbon containing material is rendered spinnable by addition of said fiber-forming high polymer, said carbon containing organic material serving as the source of carbon for the carbon fiber; the fiber may thereafter be graphitized. The spinning solution used for fiber production is preferably a solution in a volatile solvent so that it may be dry spun. The carbon source in said solvent by itself would not be spinnable and may be a monomer or low polymer.
