ABSTRACT:
An improved denture fixative composition comprising an adhesion promoter and a highly cross-linked copolymer of a lower alkyl vinyl ether and maleic anhydride or acid is disclosed wherein at least 65.0% of the total number of initial carboxyl groups in the copolymer are reacted. The cross-linking agent employed in this invention is calcium cation and optionally up to about 30.0% of the calcium function can be replaced with other inorganic cross-linking agents or polyhydroxy compounds either singly or in combination. The adhesion promoters are chelating agents such as polycarboxylic acids, hydroxycarboxylic acids, aminocarboxylic acids, polyphosphoric acids and their alkali salts.
