Polymeric or Oligomeric Active Ingredients Having a Biocidal Effect, Method for the Production Thereof, and Composition Comprising a Polymeric or Oligomeric Active Ingredient

Polymeric or oligomeric active agents with a biocidal effect which are obtainable via the polycondensation of a guanidine acid addition salt with

• one individual amine compound, whereby homopolymers of said active agents are formed, or
• an amine mixture comprising one first component and at least one second component, whereby
• copolymers of said active agents are formed,
• the first component is a diamine comprising at least one cycloaliphatic residue, or a dialkylenetriamine,
• the second component is selected from the group consisting of a diamine comprising at least one cycloaliphatic residue, a dialkylenetriamine, an alkylenediamine, and an oxyalkylenediamine, and
• the first component is different than the second component. at least one diamine and/or one triamine, wherein at least one amine is selected from the group comprising i) diamine, comprising at least one cycloaliphatic residue, and ii) dialkylenetriamine.
