P7283S01/9 PD-3902-03-CAG ABSTRACT OF THE DISCLOSURE An improved anhydrous denture adhesive composition is prepared to contain a mixture of a cationic acrylamide polymer, sodium carboxymethylcellulose and a mixed, calcium/sodium partial salt of poly(methyl vinyl ether/maleic acid). The composition may be formulated as a powder or anhydrous paste, which when applied to dentures and exposed to moisture, develops superior adhesive properties. Suitable cationic acrylamide polymers include a copolymer of acrylamide and Beta-acryloyloxyethyltrimethyl- ammonium chloride, or a copolymer of acrylamide and the reaction product of dimethylaminoethyl methacrylate and dimethyl sulfate.
