Patent

CA 2098826

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 9.9 % zinc or strontium cations; and (b) from about 20 % to about 67 % calcium 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 stabilisatrices renfermant des sels partiels mixtes spécifiques d'un copolymère d'éther-oxyde d'alkyle inférieur et de vinyle avec de l'acide maléique, où les sels partiels renferment entre environ 15 % et 40 % d'acide libre, et, comme sel cationique : (a) environ 0,1 % à 9,9 % de cations de zinc ou de strontium; (b) environ 20 % à 67 % de cations de calcium par rapport au total de groupes carboxyles initiaux ayant réagi. L'invention présente également des compositions pour la stabilisation des dents, renfermant une quantité sécuritaire et efficacement adhésive de deux ou plusieurs constituants adhésifs dentaires, dont l'un est constitué des sels mixtes partiels de la présente invention.
