| Résumé : |
Two derivatives of acrylamide, namely : N-hydroxymethylacrylamide and N,N'-(1,2-dihydroxyethylene)-bisacrylamide, were found to react rapidly and, at least in part, irreversibly with hide and skin collagen. As measured by shrinkage temperature, the two compounds effectively crosslinked the collagen and, with proper control, could serve as tanning agents. The reaction takes place under alkaline conditions but swelling of the protein was controlled by the addition of sodium sulfate to the reaction mixtures. Shrinkage temperatures of 85°C and higher were obtained. The products exhibited the required resistance to chemical and enzymic attack and, on a scale, were made into white or pale yellow leather, respectively. The results were compared to those obtained with formaldehyde and glyoxal. |
