Metal surface treatment

The invention relates to the use of at least one polymer P for treating a metal surface intended to be coated with a coating, varnish or adhesive, for example a metal surface intended to be bonded to another surface by an adhesive, in order to impart adhesion failure resistance to the resulting bond, the at least one polymer is obtained by radical copolymerization of a mixture of (i) acrylic acid; (ii) methacrylic acid; and (iii) at least one monomer having the following formula. 本发明涉及至少一种聚合物P用于处理旨在被涂料、清漆或粘合剂涂覆的金属表面，例如旨在被粘合剂粘结至另一个表面的金属表面，以便赋予所得的粘结抗粘合失效性的用途，该至少一种聚合物是通过以下项的混合物的自由基共聚获得的：(i)丙烯酸；(ii)甲基丙烯酸；以及(iii)至少一种具有下式的单体：。
