Abstract
Highly polymerised sulphate polysaccharides are prepd. from polysaccharides of natural origin. These are treated with a (di:methyl-formamide) -(sulphur-tri:oxide) complex at 5-10 deg.C in di:methyl-formamide. The obtd. poly-saccharide sulphate is converted to a salt when aq. soln. of mixed alkali metal, alkaline-earth-metal and/or a trivalent carbonate is added. - Opt. salt solns. of other metals, namely Rb, Cs, Fe(III), Mn(II), Zn(II) and Mo(IV) are added.
