PROCESS FOR THE PREPARATION OF MESOPHASE PITCHES

A process for the preparation of an excellent mesophase pitch suitable for use as a spinning pitch for the production of high performance carbon fibers is disclosed. The mesophase pitch can satisfy the four remarkable characteristics at the same time, i.e., a softening point of below 320 DEG C as de...
