| 摘要 |
This invention describes a substantially homogeneous, optically anisotropic carbonaceous pitch characterized in that the major portion of said pitch consists of a continuous, optically anisotropic phase, said optically anisotropic phase contains spherules of an optically isotropic phase having diameters of not more than about 100 mu m and dispersed in said optically anisotropic phase, the content of said optically isotropic spherules is up to about 20% on the basis of said pitch as a whole, said pitch contains at least about 30 wt % (based on said pitch) of a quinoline-soluble component, and said pitch has a lower softening point.
