Abstract
The present invention relates to modified comb copolymers comprising special structural units, which are produced by converting SMA resins and optionally special copolymers with an AB block copolymer structure with a mixture of at least one polyalkylene oxide monoamine and at least one amino alcohol, with a mixture of at least one polyalkylene oxide monoamine and at least one N,N-disubstituted diamine or a mixture of at least one polyalkylene oxide monoamine, at least one N,N-disubstituted diamine and at least one polymer selected from the group comprising monohydroxy-terminated polyalkylene oxides, monohydroxy-terminated polyesters and monohydroxy-terminated block copolymers comprising polyalkylene oxide and polyester blocks, and their monohydroxy-terminated side chains are converted to phosphoric acid ester groups or their N,N-disubstituted amino-terminated side chains are converted to quaternary ammonium salts, and their use as wetting and dispersing agents.
