| abstract |
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 R 1 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) -CH 2 -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. |
