ABSTRACT:
Producing carbon fiber precursors and carbonized fibers comprise by treating a thin film of catalytic pitch at elevated temperature conditions, treating the resulting heavy isotropic pitch by agitating with an inert gas under elevated temperature conditions to form a mesophase pitch, forming green fibers from said mesophase pitch, stabilizing and optionally carbonizing said green fibers to obtain the desired product.
