抄録

A carbonaceous anisotropic mesophase, highly soluble in THF and quinoline, was prepared from ethylene tar pitch (ETP) modified using aluminum chloride as a catalyst. A mesophase pitch prepared at 360°C under vigorous nitrogen flow and stirring from ETP modified with 10 wt% of AlCl3 at 250°C for 7 hr exhibited solubility of 80 wt% in quinoline at 90 vol% of anisotropic content, its solubilities in THF and pyridine being as high as 52 and 62 wt%, respectively. Such a high solubility of the mesophase pitch is ascribed to the naphthenic groups of its component molecules which are produced during the modifying reaction catalyzed by AlCl3. The moderate molecular size of modified ETP is another advantage. The anisotropic mesophase of high solubility and low melting temperature is transformable into a flow domain texture by annealing. Easy spinning into highly oriented fibers is expected.
