Abstract

Method for the preparation of a mouldable composition for the production of permanent magnets, with high temperatures of thermal deformation, characterized in that it comprises treating a permanent immanent material, in final division; and an epoxy resin and phenolic resin composition, which composition comprises an epoxide resin prepared by reacting a polyphenolic compound with an epoxide compound; a permanently fusible phenol/formaldehyde resin; and a hydroxyalkyl tertiary aliphatic amine, prepared by reaction of a low molecular weight epoxide with an aliphatic amine; this tertiary amine is present in catalytic amount.
