Polymeric or oligomeric active ingredients having a biocidal effect, method for the production thereof, and composition comprising a polymeric or oligomeric active ingredient
The invention relates to novel polymeric or oligomeric active ingredients having a biocidal effect. Such especially advantageous polymeric or oligomeric active ingredients having a biocidal effect can be obtained by polycondensating a guanidine acid addition salt with an amine mixture, which contains at least one diamine and/or one triamine, wherein at least one amine is selected from the group comprising i) diamine, which has at least one alicyclic group, and ii) dialkylenetriamine. At least one amine is preferably selected from 4,4'-methylene-bis(cyclohexylamine) and diethylenetriamine. In addition, it is favorable if the guanidine acid addition salt is guanidine hydrochloride.
