Abstrakt: | Colagen hydrolyzate was crosslinked with diepoxibutane or (octane) at 25oC. Suitable conditions for crosslinking were found at pH = 9. Solubility of samples decreased proportionately with increasing concentration of crosslinking agent. Viscosity measurements yielded best results for estimation of intrinsic viscosity in 1M KCl solution. Diepoxyoctane was better crosslinking agent than diepoxybutane. In IR spectra crosslinking demonstrated only weakly with diepoxyoctane. | ||||||||||
