| 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 each X independently represents a leaving group; each R1 independently represents either an aromatic ring system with at least one aromatic ring, optionally containing one or more hetero atoms selected from 0, N and S and optionally being substituted with one or two vinyl groups to which the -CH2-X group(s) is/are bound, or represents ethylene; Gua represents a guanidindiyl, aminoguanidindiyl or diaminoguanidindiyl residue; Y represent H-Gua, and Z represents H; or Y and Z together represent a chemical bond to obtain a cyclic structure; wherein at least one benzyl or allyl derivative BA is subjected to a polycondensation reaction with excessive guanidine, aminoguanidine or diaminoguanidine G upon elimination of HX. |
