Abstract

Macromolecular compositions cross-linked by a new sequence having the formula -NR<sx>s-CH = N-CO-. The new sequence is obtained by reacting a macromolecule, in particular a polymer macromolecule, which contains at least two aminocarbonyl groups, with a compound containing at least two formylamido groups, in a strongly acid aqueous medium. This new sequence is formed through a chemical reaction according to the following equation: (FORMULA) The compositions according to the invention, containing on the one hand macromolecular compounds which have at least two amidocarbonyl groups, and containing on the other hand a compound which has at least two formylamino groups, may be used as thickening agents or as gelatinizing agents for water-diluted acids. Following the mixing of these components, in the presence of water-diluted acids, a cross-linking reaction takes place as described above, and results in the new sequence which forms the cross-linking bridge. The acids so thickened of gelatinized are preferably used in oil and natural gaz extraction from underground fields.
