Binding properties of the mesophase pitches produced catalytically from naphthalene with HF/BFJ were examined in terms of their carbon value, fluidity, thermal stability, and oxidative stabilization reactivity. The present pitches with 100% anisotrophy and low softening points of 207-275ยฐC provided
Mesophase pitch-based carbon fibres thermoset with CI2 containing air were studied for their microstructures and physical properties. Carbon fibres thermoset with CI2 containing air and heat-treated at 2000 ~ (CI22000) possessed slightly smaller mean sizes of crystallites Lc(0 0 2)s, lower densities
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
