Abstract
The instant invention concerns the use of polymers obtained by radical copolymerization of a mixture of (1) acrylic acid; (2) methacrylic acid; and (3) at least one allylcatechol selected from 4-allylbenzene-1,2-diol, 3-allylbenzene-1,2-diol; methylated forms thereof (eugenols); and mixtures thereof, for treating a metallic surface intended to be adhesive-bonded to another surface, in order to impart a resistance to the adhesive failure to the resulting bonding.
