Abstract: Provided are a method for manufacturing a high yield and high performance mesophase pitch and a high yield and high performance mesophase pitch manufactured therefrom by hydrogenating, mesophase formation, thin film evaporation, solvent-extracting, filtering and then drying to obtain only mesogen components in flow-domained mesophase pitch and then mixing the mesogen components with an isotropic pitch as a solvent component. Further, the high yield mesophase pitch of the present disclosure exhibits high spinnability while maintaining whole anisotropy and exhibits a much higher production yield than existing mesophase pitches.
