The invention provides a solid support-polymer comprising two or more residues of formulae III or IV, or salts thereof: (III) (IV) wherein the residues of formulae III or IV are covalently attached to a solid support. The dash line, X, Y, Q, L, M, n, R1, R2, Ra, Rb, Rc and Rd have any of the values defined in the specification, as well as synthetic intermediates and synthetic methods useful for preparing the compounds. The polymer is useful to treat contaminated water by chelating metal. L'invention concerne un polymère de support solide comprenant au moins deux résidus de formules III ou IV, ou des sels associés : (III) (IV), les résidus des formules III ou IV étant liés de manière covalente à un support solide. La ligne de pointillés, R1, R2, Ra, Rb, Rc and Rd adoptent une valeur quelconque parmi les valeurs définies dans la spécification. L'invention concerne également des intermédiaires de synthèse et des procédés de synthèse utiles pour la préparation desdits composés. Le polymère est utile pour le traitement de l'eau contaminée par chélation de métal.
