PROCESS OF PRODUCING OPTICALLY ANISOTROPIC CARBONACEOUS PITCH |
| 摘要 |
<p>A homogeneous, optically anisotropic pitch used for the production of carbon materials is prepared from a starting oil comprising a substantially chloroforminsoluble matter-free oily or tarry substance. The starting oil is subjected to thermal cracking and polycondensation to form approximately 20-80% of optically anisotropic phase pitch.</p> |
