Carbonization of oxidized mesophase pitches originating from petroleum and coal tar was examined by thermogravimetry, FT-i.r. spectroscopy, and quantitative analysis of evolved gases. Polymerization and condensation of aromatic rings through loss of aromatic hydrogen are shown to be major chemical r
The transverse structure of pitch fiber has been successfully controlled by changing the pitch flow conditions at the upper portion of the capillary in spinning. The mean size of mesophase domains in the transverse section of pitch rod extruded from the capillary was found to decrease monotonously w
