Abstract: An epichlorohydrinamine polymer has a ratio of amine units to epichlorohydrin units of from 0.8:1.2 to 1.0:1.0, dimethylaminopropylamine and benzylamine preferably being used as amine and/or ammonium units. The novel epichlorohydrinamine polymer is used, for example, for the surface treatment of semifinished leather products and textile materials.
