A process for the production of a shaped article having magnetic properties from a composition which comprises a mixture of a solid melt-processable and cross-linkable organic material and a particulate magnetic material, which process comprises the steps of (1) shaping the composition in a mould at a temperature at which organic material is in a fluid state, (2) cooling the thus shaped composition so as to solidify the organic material, and (3) cross-linking the organic material in the thus-shaped composition to produce a cross-linked material. Also, a composition as described which also contains a polymeric material which is soluble in or dispersible in the organic material when the organic material is in a liquid state. |
