The invention relates to a method for producing polycondensation products of guanidine, aminoguanidine or diaminoguanidine G with one or more benzyl- or allyl-derivatives BA according to the following reaction scheme: wherein X represents, respectively independently, a leaving group； each R1 represents independently either an aromatic ring system with at least one aromatic ring, which optionally contains one or more heteroatoms selected from 0, N and S and which is optionally substituted with one or two vinyl groups, to which the group(s) -CH2-X is/are bound, or represents ethylene； Gua represents a guanidindiyl-, aminoguanidindiyl- or Ddaminoguanidindiyl-group； Y represent H-Gua and Z represents H； or Y and Z together represent a chemical bond in order to produce a cyclic structure； wherein at least one benzyl- or allyl-derivative BA is subjected to a polycondensation reaction with an excess of guanidine, aminoguanidine or diaminoguanidine G with the elimination of HX.Mevcut buluş, poliguanidinlerin üretimine yönelik yeni bir usul ile, bu şekilde üretilen polikondensasyon ürünleri ile ve bunların anti-mikrobiyal veya anti-enfektif ajanlar olarak kullanımı ile ilgilidir.
