摘要

Process for the manufacture of an adhesive based on a mixed polymer of butadiene and acrylonitrile, mixed with a heat-curable resin, of the phenolformaldehyde type, the aforementioned adhesive especially allocating to the attachment of copper and sheets of this material with other objects , as well as to the fabrication of electrical devices composed of copper sheets and phenol-formaldehyde resins, which is characterized in that said mixed polymer and the thermosetting resin are contacted with a monocarboxylic acid, aliphatic, containing 1 to 4 carbon atoms, under such operating conditions that the rescue combination has a proportion of 5 to 60% by weight of said acid, in relation to the dry weight of the adhesive.
