Abstract of the Disclosure The calcium salts of the solid cyclic copolymers of divinyl ether and maleic anhydride, soluble in water, have been found to be as effective in treating tumors and viruses as the prior art alkali metal salts (e.g., the sodium salt) but much less toxic. These copolymers are characterized by containing divinyl ether and maleic anhydride in a mole ratio of about 1:2, having a molecular weight of from about 2000 to about 100,000 and from about 5% to about 70% of its carboxylic acid groups converted to calcium salts.
