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
properties of mesophase pitches were examined using a capillary rheometry at the temperature range of their spinning to clarify influences of temperature, dimension of capillary, and structure and molecular assembly of the mesophase pitch. The viscosity-shear rate correlation curves of mesophase pit
