Title: Processes for producing saccharide derivatives using solid ultrastrong acid

Abstract: This invention provides glycoside polymers or glycosides which are useful as a material for functional foods, biodegradable fibers or medicaments, said glycoside polymers being produced efficiently by subjecting a compound of the formula (1): ##STR1## wherein R.sup.1 is --OH, R.sup.2 is --OH or --NHCOCH.sub.3, R.sup.3 is --CH.sub.2 OH, --COOH or --CH.sub.3, to a melt polymerization or a solution polymerization in the presence of a solid superacid, and said glycosides being produced by reacting the compound (1) with a saturated or unsaturated alcohol in the presence of a solid superacid.
