“…This is in contrast to the results obtained from a similar polymer (poly(hexamethylene guanidine) hydrochloride), using calculations based on sedimentation data indicating M w s of about 10 000. [7,8] Vapor pressure osmometry of poly-(hexamethylene guanidine) hydrochloride and poly(hexamethylene biguanidine) hydrochloride gave M w s in the range of 1 000 to 3 000, depending on the reaction time. [9] As can be seen from Figure 2, there are four major product-type series, which can be best described with the structures displayed in Figure 1.…”

Oligomeric guanidines can be obtained by polycondensation of guanidine hydrochloride and 1,2‐bis(2‐aminoethoxy)ethane. A comparative MALDI‐TOF mass spectrometry/NMR spectroscopy study with a 13C‐labeled sample enabled the unambiguous analysis of a guanidine‐based polymer. Among the four major product series unprecedented macrocyclic compounds were detected. The minimum inhibition concentrations for four different microorganisms were determined, showing excellent biocidal activities. magnified image

Copolymers of polyguanidines with various lengths of hydrocarbon radicals were obtained by polycondensation. The biocidal action of water-soluble, guanidine-containing copolymers on the pathogenic microorganisms Escherichia coli and Bacillus cereus by the method of agar diffusion was evaluated. The results indicate that the ratio of hydrophobic methylene groups to ionogen guanidine groups influenced the copolymer biocidal action.

“…However, data about methods of synthesis of such type modified silicas and their adsorption properties are currently unknown. We have taken into account the fact that synthesis of polyhexamethyleneguanidine is usually implemented via the condensation reaction of guanidine hydrochloride with hexamethylenediamine [11].…”
