Otani, S

A novel carbonaceous pitch which is optically isotropic in nature and which turns into optically anisotropic when shear forces are applied thereto. The carbonaceous pitch may be obtained by hydrogenating the mesophase of a mesophase pitch to the extent that the mesophase is rendered soluble in quinoline. The carbonaceous pitch is used as a binder and an impregnator and as a precursor material for a highly oriented, high-strength and high-modulus carbon fiber, needle coke or the like carbonaceous materials.
