Abstract: The present invention provides a process for thermosetting pitch fibers in reduced times, at low concentrations of oxygen and at higher temperatures than previously possible. Additionally, the present invention provides a pitch fiber which has an oxygen diffusion rate to the center of the fiber which is competitive with the rate of oxidation a t the fiber's surface. Further, the present invention provides a high density pitch fiber batt which thermosets without loss of fiber structure.

Abstract: This invention provides a process for preparing a solvated isotropic pitch having a fluid temperature at least 40 .degree.C lower than the same pitch in the non-solvated state. Additionally, the present invention provides a solvated isotropic pitch which may be formed into carbon artifacts which do not require oxidative stabilization prior to carbonization.

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.

Abstract: US0118523ng component for a solvated mesophase pitch. The solvated component includes a mixture of aromatic hydrocarbons having boiling points in the atmospheric equivalent boiling point range of about 285~ to about 460 ~C (about 550 ~F - 932 ~F). At least 80 % of the carbon atoms of the hydrocarbo ns are aromatic as characterized by carbon 13 NMR. The aromatic hydrocarbons ar e selected from a group consisting of aromatic compounds having 2 to 5 aromati c rings, substituted aromatic compounds having 2 to 5 aromatic rings wherein said substituents are alkyl groups having 1 to 3 carbons, hydroaromatic compounds having 2 to 5 rings, substituted aromatic compound having 2 to 5 rings wherein said substituents are alkyl groups having 1 to 3 carbons, and mixtures thereof.
