    Abstract: This invention relates to low melting solvated mesophase pitches which are suitable for spinning into carbon fibers. The solvated mesophase pitches have a lower melting point than conventional mesophase pitch but remain substantially anisotropic. The solvated mesophase can be produced as an intermediate during solvent fractionation or supercritical solvent fractionation of mesogen-containing isotropic pitches. The process is enhanced through the ability to recover pseudomesogens with an increased average molecular weight which, in combination with the solvent content, provides a fusible mesophase capable of being spun directly into infusible oriented anisotropic carbon fibers.
