Abstract
THE introduction of cross-linkages into soluble synthetic linear high polymers is followed by a decrease in solubility. In Nature, an interesting parallel appears to be afforded on one hand by the water-soluble polysaccharide lichenin, which consists of an unbranched ß-glucopyranose chain (C6H10O5)n where n = 80-1601, 2 and by cellulose on the other, if for the latter the structure of ß-glucopyranose chains (or multi-membered loops) linked at intervals by cross-linkages3 be accepted. This communication contributes to the question of the structural difference between lichenin and cellulose.
