A polycondensation product of aminoguanidine and / or 1,3-diaminoguanidine with one or more diamines, wherein the polycondensation product is a polyguanidine derivative of the following formula (I): ** Formula ** in which X is selected of -NH2, aminoguanidino and 1,3-diaminoguanidino; Y is selected from -H and -R1-NH2; or X and Y together represent a chemical bond, to generate a cyclic structure; R1 is selected from divalent organic residues with 2 to 20 carbon atoms, where one or more carbon atoms are optionally replaced by O or N; A and b are each 0 or 1, where a + b ≠ 2 when 1,3-diaminoguanidine units are not included; R2 is selected from -H and -NH2, where R2-NH2, if a + b = 0, R2 is -H or -NH2, if a + b = 1 and R2 is -H, if a + b = 2; and n> = 2; or a salt thereof. |
