Structural adhesive based on an acrylic reactant

Double-component structural adhesives, based on an acrylic reactant, which comprise:

• (a) a first adhesive component constituted by a solution of a chlorosulfonated polymer in a mono-functional acrylic monomer containing a free-radical generator agent, a stabilizer agent, an adhesion promoter and a crosslinker selected from among silicon derivatives falling within the scope of the following general formulae:
• ##STR2## wherein:
• R.sub.1 represents an alkyl radical of from 1 to 4 carbon atoms,
• R.sub.2 represents an alkyl radical of from 1 to 4 carbon atoms or a phenyl radical,
• Y represents an oxygen bridge, an amino group or an alkylene radical of from 1 to 12 carbon atoms,
• n is an integer comprised within the range of from 1 to 50;
• (b) a second component, which activates the adhesive component, constituted by a mixture of aldehyde-amine condensation products, in which an organic salt of a metal belonging to the first transition series, in a low oxidation state, is dissolved.
