Beschreibung
Zusammenfassung:	PURPOSE:To obtain a magnet, etc. of excellent magnetic characteistics in which larger amount of magnetic powder is filled up by adding an organic metal compound having amino groups and bisamido to a kind of magnetic material composed of nylon and magnetic powder. CONSTITUTION:A kind of magnetic material composed of nylon and magnetic material is further added with an organic metal compound having amino groups and bisamido. As a result of this, its melting viscosity considerably falls by the synergistic effect of those ingredients, and its forming workability is not impaired even if larger amount of magnetic powder than ever is mixed. Consequently, a magnet, etc. of excellent magnetic characteristics in which larger amount of magnetic powder is filled up can be obtained. This feature can be obtained only when an organic metal compound having amino groups and bisamido are concurrently used, and if either one is absent, such a remarkable effect cannot be attained.
