[ What is claimed is:] [1.] A denture adhesive composition consisting essentially of a partial, mixed salt of an alkyl vinyl ether and maleic acid copolymer wherein a stochiometric excess of acid groups remains after salt formation is complete, and wherein the cations of said salt comprise:a) calcium with a degree of substitution of the copolymer in calcium about 71% or higher; andb) at least one other cation selected from the group consisting of sodium and potassium; and wherein the degree of substitution of said copolymer in said at least one other cation is greater than about 2% and less than about 10%.
