FIELD : chemistry.SUBSTANCE : invention refers to polymer ligand with athranilamide main-chain units and to metal polymer complex wherein polymer ligand forms luminescent complexes with rare earth ions. Polymer ligand is described with the general formula -(A-B)m- : where A is a fragment of methylene-bis-anthranilic acid, B is a fragment of dicarboxylic acid chosen from dicarboxylic acid series, R= -(CH2)6-, -(CH2)7-, -(CH2)8-, m refers to values MM within 80 kDa to 200 kDa. Metal polymer complex based on polymer ligand is described with the general formula -(A-B)m-Me : , where A is a fragment of methylene-bis-anthranilic acid, B is a fragment of dicarboxylic acid chosen from dicarboxylic acid series, , m refers to values MM within 80 kDa to 200 kDa, Me is rare-earth metal from the group including Tb3+ and Eu3+, in ratio metal ion : metal polymer complex, wt % 0.3-3.9.EFFECT : invention allows for high-strength metal polymer complex of improved thermal stability and luminescence intensity.2 cl, 2 tbl, 12 ex, 6 dwg
