    摘要： Denture adhesive compositions having good hold and improved taste containing a salt of a copolymer of alkyl vinyl ether-maleic acid or anhydride. Compositions containing from about 25% to about 45%, by weight of the composition, of a salt of a copolymer of alkyl vinyl ether-maleic acid or anhydride containing a cationic salt function containing: i) from about 60% to about 72% cations selected from calcium, strontium, magnesium, or combinations thereof; ii) from 0% to about 10% sodium cations; iii) less than 1% zinc cations; and iv) from about 25% to about 40% of a free acid component; and further containing from about 15% to about 25%, by weight of the composition of a carboxymethyl cellulose having a molecular weight of from about 200,000 to about 1,000,000 daltons; and a carrier. Methods of improving the adhesion of dentures to the oral cavity by applying such compositions to dentures, the oral cavity, or both, and thereafter securing the denture to the ridge or palate of the oral cavity.
