Document Type and Number:
Japanese Patent JP2679010
Kind Code:
B2
Abstract:
An organic ferromagnetic substance and a process for producing same are disclosed, which substance comprises a carbonaceous substance of at least one polymer in mid course of graphitization selected from (a) an aromatic polymer having a structure such that the aromatic compounds are connected via alkylene chains which may be substituted by an alkyl or aryl group, (b) a polymer of a triarymethane, (c) a polymer of an acetylene compound and (d) a polymer of an alpha , beta -unsaturated compound, characterized in that the carbonaceous substance contains 1-10 hydrogen atoms per 100 carbon atoms. This organic ferromagnetic substance can be produced in a high yield from commercially available polymers in a simple manner and possesses excellent stability to heat, chemicals and weathering action. Accordingly, this substance can be used in various industrial fields.
