Abstract

Separation process yields anisotropic pitches without orientated anisotropic droplets. Laboratory and industrial pitches (D1, D2, E1, and E2) were characterized and compared to two experimental pitches. The latter were obtained by fractionation of the two component pitches B3 and C by toluene. After graphitization, the fibers issued from these pitches are entirely devoided of zig-zag. However they are rich in disclinations distributed at random. The amount of final disclinations largely overcome the amount already present in the initial pitch. The physicochemical properties of these pitches, their preparation procedure, the textures at various scales of the derived fibers, and their graphitizability as well as compared to those studied in part I.
