AbstractA process for producing pitch useful as a starting material for the manufacture of a carbon material is provided. The pitch is produced by polymerizing a condensed nuclear aromatic compound or a material containing the same. The polymerization is carried out in the presence of a hydrogen fluoride/boron trifluoride catalyst system. The condensed nuclear aromatic compounds which may be used in this process are naphthalene, anthracene, phenanthrene, acenaphthene, acenaphthylene, pyrene and mixtures thereof.
