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.
