Abstract: Denture adhesive compositions with sufficient initial adhesion to the gums that build up enough cohesive strength upon hydration with saliva to withstand the stresses occurring during food mastication and cushions the gums from contact with the denture during chewing. The adhesive comprises a mixed partial salt of an amino ethyl ethylene urea substituted polyalkylvinylether/maleic acid copolymer wherein the cations of the salt are selected from the group consisting of zinc, calcium, magnesium, strontium, zirconium, sodium, and potassium.

Abstract: A denture adhesive liner in the form of an extruded film or sheet comprising (a) a denture adhesive effective amount of a mixed partial salt of a copolymer of maleic acid and an alkyl vinyl ether and at least one cation, wherein all of said cations are selected from the group consisting of sodium, potassium, calcium, strontium, magnesium, zinc and zirconium oxy cations; (b) between about 30 and 90 wt. % of a thermoplastic polymer component; and (c) a plasticizer; wherein said composition is extrudable into a film that is capable of adhering to a wet mucous surface and/or acrylic plastic.
