摘要：
Catechol-group-containing polymers with amine or amide functionality, containing at least one repeating unit of the formula (I) and at least one repeating unit of the formula (II) and optionally further repeating units
The repeating units of the formula (II) are different from the repeating units of the formula (I) and the molar ratio of the units of the formula (I) to the units of the formula (II) is in the range from 0.5-to-1 to 4-to-1, are suitable for the dirt-repellent finishing of substrate surfaces, particularly surfaces of textiles, glass, ceramics or plastics. The polymers have an excellent adhesion to these surfaces, so that during cleaning of a substrate surface they adsorb to the substrate surface from the aqueous cleaning or washing liquor and realize their effect.
