Invention relates to obtaining crystalline polymers of epoxybisphenol A resins, which can be used in production of permanent magnets from powder materials, and also in other areas of technology, where epoxies with higher physicomechanical properties are required. Is known the method of obtaining polymers of epoxybisphenol A resins by solidification during the heating in the magnetic field of the composition, which contains resin, hardener, and, as the filler, extended particles of iron. Polymers obtained in this case have amorphous structure. It is known that crystalline polymers exceed amorphous ones in their technical characteristics.
