Water-soluble polymers having a molecular weight in the range of 100,000 to 2,000,000 including homopolymers and copolymers of vinylbenzenesulfonic acids and salts thereof wherein the benzene ring may be substituted by various radicals, compositions containing said products and methods useful in the treatment of ulcers are disclosed. The products are prepared by polymerization or copolymerization of vinylbenzene or substituted vinylbenzene followed by sulfonation or alternatively by the polymerization or copolymerization of substituted or unsubstituted vinylbenzenesulfonic acid salts. |
