A new crosslinking agent for cellulose, bis-isocyanatomethyl disulfide (BIMD), was synthesized from dithiodiacetyl dihydrazide. Both O-methyl and ethyl urethanes produced by the reaction of BIMD with methanol and ethanol showed a C-H absorption peak at unusually high wave length (3060cm-1) in their infrared spectra.
