Patent

CA 2109624

Disclosed are stabilizer compositions comprising specific mixed partial salts of a lower alkyl vinyl ether-maleic acid copolymer wherein said partial salts containing from about 15% to about 40% free acid, and as the cationic salt function; (a) from about 0.1 % to about 80% strontium cations; and (b) from about 0.1 % to about 65% zinc cations of the total initial carboxyl groups reacted. Also disclosed are denture stabilizing compositions comprising these mixed partial salts, as well as denture stabilizing compositions comprising a safe and adhesively effective amount of two or more denture adhesive components wherein one of said denture adhesive components is the mixed partial salt(s) of the present invention.

Compositions renfermant des sels partiels mixtes spécifiques d'un copolymère d'acide maléique et d'éther-oxyde de vinyle et d'alkyle inférieur, où les sels partiels renferment environ 15 % à 40 % d'acide libre, et comme sel cationique (a) environ 0,1 % à 80 % de cations strontium, et (b) environ 0,1 % à 65 % de cations zinc sur le total initial de groupes carboxyles ayant réagi. L'invention porte également sur des compositions stabilisatrices pour les dents, renfermant ces sels partiels mixtes, ainsi que sur des compositions stabilisatrices pour les dents renfermant une quantité sûre et efficace de deux ou plusieurs constituants adhésifs pour les dents, dont l'un est le sel partiel mixte de la présente invention.
