Abstract
Abstract Disclosed is a process for producing graphite, which comprises heat treating at least one polymer selected from the group consisting of a polyphenyleneoxadiazole, polybenzothiazoles, a polybenzobisthiazole, a polybenzoxazole, a polybenzobisoxazole and a polythiazole. …<??>This process can provide almost perfect graphite which could not conventionally be obtained, by an extremely simple procedure in which the polymer is merely heat treated, without the conventional preliminary oxidation treatment. Further, according to this process, graphite in any shape, namely film-shaped, fibrous or powdered, can be easily produced in compliance with request.
