Abstract
(EN)
The instant invention concerns 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-allyl benzene-1,2-diol and mixtures thereof. The polymers are especially useful for treating a metallic surface intended to be coated by a paint, a varnish or an adhesive. The invention also concerns methods of coatings making use of this polymer P, compositions comprising the polymer P and useful for these methods, and the obtained coated materials.

La présente invention concerne des polymères obtenus par copolymérisation radicalaire d'un mélange (1) d'acide acrylique ; (2) d'acide méthacrylique ; et (3) d'au moins un allylcatéchol choisi parmi le 4-allylbenzène -1,2-diol, le 3-allyl benzène -1,2-diol et leurs mélanges. Les polymères sont particulièrement utiles pour le traitement d'une surface métallique destinée à être revêtue par une peinture, un vernis ou un adhésif. L'invention concerne également des procédés de revêtements utilisant ce polymère P, des compositions comprenant le polymère P et utiles pour ces procédés, et les matériaux revêtus obtenus.
