Polymer composition

A polymer composition which is obtained by neutralizing a polymer P having at least one functional moiety of the formula (I):

• bound to the termini and/or to the backbone of a polymer, where
• # indicates the point of attachment to the terminus of the polymer and/or to the polymer backbone;
• k is 0, 1, 2, 3 or 4;
• m is 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9;
• A is a chemical bond or a divalent moiety selected from the group consisting of C1-C6 alkylene, —O—(C2-C6 alkylene), —C(═O)—O—(C2-C6 alkylene), —NR3—(C2-C6 alkylene) and C(═O)—NR3—(C2-C6 alkylene), where the C2-C6 alkylene part is attached to Q;
• Q is a divalent moiety selected from the group consisting of —O—, —NH— and —S—;
• R1 is independently selected from the group consisting of —OH, —COOCH3, —NO2, —S(═O)2R4, C1-C20 alkyl, C1-C4 alkoxy, halogen, aryloxy, aryl, heteroaryl, where aryl, heteroaryl and aryloxy are unsubstituted or substituted by 1, 2, 3 or 4 radicals selected from the group consisting of —OH, COOH, —COOCH3, —NO2, —S(═O)2R4, C1-C4 alkyl, C1-C4 alkoxy and halogen;
• R2 is selected from the group consisting of hydrogen, —S(═O)2R4, C1-C20 alkyl, C3-C10 cycloalkyl, aryl, heteroaryl, aryl-C1-C4-alkyl and heteroaryl-C1-C4-alkyl, where aryl and heteroaryl in the four last mentioned radicals are unsubstituted or substituted by 1, 2, 3 or 4 radicals selected from the group consisting of —OH,COOH, —COOCH3, —NO2, —S(═O)2R4, C1-C4 alkyl, C1-C4 alkoxy and halogen;
• X is a divalent moiety selected from the group consisting of linear C1-C10 alkylene, linear C2-C6 alkenylene, C4-C7 cycloalkylene, arylene and alkarylene, where the linear C1-C10 alkylene, linear C2-C6 alkenylene and C4-C7 cycloalkylene are unsubstituted or substituted by 1, 2, 3 or 4 radicals selected from the group consisting of C1-C18 alkyl or C1-C18 alkenyl, and where arylene and alkarylene are unsubstituted or substituted by 1, 2, 3 or 4 radicals selected from the group consisting of C1-C4 alkyl, C1-C4 haloalkyl, aryl, —COOH, —COOCH3, —NO2 and halogen;
• R3 is selected from the group consisting of hydrogen, —S(═O)2R4, C1-C20 alkyl, C3-C10 cycloalkyl, aryl and heteroaryl, where aryl and heteroaryl are unsubstituted or substituted by 1, 2, 3 or 4 radicals selected from the group consisting of —OH, COOH, —COOCH3, —NO2, —S(═O)2R4, C1-C4 alkyl, C1-C4 alkoxy and halogen;
• R4 is selected from the group consisting of OH, C1-C4 alkyl, C1-C4 alkoxy, aryl and heteroaryl, where aryl and heteroaryl are unsubstituted or substituted by 1, 2, 3 or 4 radicals selected from the group consisting of C1-C4 alkyl, C1-C4 alkoxy and halogen;
• with an oligomeric or polymeric amine PA having at least 2 amine groups per molecule.
