(FR) COMPOSITION DE POLYMÈRE DE POLYACRYLAMIDE GLYOXYLÉ, SON UTILISATION ET PROCÉDÉ D'AUGMENTATION DES PROPRIÉTÉS DE RÉSISTANCE DE PAPIER, CARTON OU SIMILAIRE
Abstract:
(EN) A cationic glyoxylated polyacrylamide polymer composition having improved storage stability for use in manufacture of paper, board or the like, which aqueous composition comprises a glyoxylated polyacrylamide polymer having a cationic charge density in the range of 0.8-1.8 meq/g of dry polymer in dry content of 5-15 % and a buffering acid. The aqueous composition has pH in the range of 2.2, 4.0 and a viscosity of less than 80 mPas measured at 25°C by using a Brookfield viscometer after 30 days storage at 35°C or after 60 days storage at 23°C.
(FR) La présente invention concerne une composition de polymère de polyacrylamide glyoxylé cationique ayant une stabilité à la conservation améliorée et destinée à être utilisée dans la fabrication de papier, carton ou similaire, ladite composition aqueuse comprenant un polymère de polyacrylamide glyoxylé ayant une densité de charge cationique dans la plage de 0,8 à 1,8 meq/g de polymère sec en teneur sèche de 5 à 15 % et un acide tampon. La composition aqueuse a un pH dans la plage de 2,2 à 4,0 et une viscosité inférieure à 80 mPas mesurée à 25 °C au moyen d'un viscosimètre Brookfield après 30 jours de conservation à 35 °C ou après 60 jours de conservation à 23 °C.
