L'invention concerne des copolymères (A) de monomères (a) à insaturation oléfinique, pouvant être fabriqué par copolymérisation radicalaire contrôlée à une ou plusieurs étapes en milieu aqueux de (a1) au moins un monomère à insaturation oléfinique contenant au moins un groupement formant un chélate et (a2) au moins un monomère à insaturation oléfinique différent du monomère à insaturation oléfinique (a1), choisi dans le groupe comprenant (a21) les monomères de formule générale (I) R1R2C=CR3R4 (I), dans laquelle les radicaux R1, R2, R3 et R4 représentent indépendamment les uns des autres un atome d'hydrogène ou un radical alkyle, cycloalkyle, alkylcycloalkyle, cycloalkylalkyle, aryle, alkylaryle, cycloalkylaryle, arylalkyle ou arylcycloalkyle substitué ou non substitué, à condition qu'au moins deux des variables R1, R2, R3 et R4 représentent un radical aryle, arylalkyle ou arylcycloalkyle substitué ou non substitué, notamment un radical aryle substitué ou non substitué; (a22) les hydrocarbures de terpène oléfiniques insaturés et (a23) les alpha-alkylvinylaromatiques dimères. L'invention concerne également leur procédé de fabrication et leur utilisation.
