Abstract 2,4‐O‐Benzylidene‐1,6‐dithiol‐D‐glucitol is prepared by nucleophilic displacement of tosyloxy groups from 3,5‐di‐O‐acetyl‐2,4‐O‐benzylidene‐1,6‐di‐O‐tosyl‐D‐glucitol with thioacetate in N,N‐dimethylformamide and deacetylation of the product. Oxidative polymerization with oxygen and selenium dioxide produces film‐forming disulfide polymers with intrinsic viscosities up to 0.41. Other oxidizing agents produce polymers of lower viscosity. Condensation of the dithiol with benzaldehyde also gives polymers of low viscosity.
