摘要：PURPOSE:To obtain carbon fibers, containing an optical anisotropic pha as a continuous pha in a specific proportion, stably spinnable at a high speed, and having a high strength and high elasticity, by thermally polycondensing a pitch treated with a reducing solvent. CONSTITUTION:A pitchy material, e.g. coal tar pitch or petroleum pitch, is treated with a reducing solvent, e.g. tetrahydroquinoline or tetralin, and then thermally polycondend to give the aimed mesopha pitch, containing 35- 95vol% optical anisotropic pha as a continuous pha, and having 200-300 deg.C softening point measured by a KOKA type flow tester, and spinnable at >=300 m/min spinning speed at a temperature 50-180 deg.C higher than the softening temperature. USE:Carbon fibers are obtained by spinning the pitch, and carbonizing the resultant fibers.
