(FR) PROCEDE DE FABRICATION DE PAPIER ET ADDITIF ASSOCIE
Abstract: front page image
(EN)A papermaking additive comprising: (A) a cationic acrylamide polymer prepared by the reaction of an acrylamide polymer with a hypohalite under an alkaline condition in a temperature range of 50 to 110 °C for a short time, and (B) either an anionic inorganic substance or a cationic polyacrylamide prepared by the copolymerization of a cationic monomer such as an acrylic ester or acrylamide derivative, an $g(a),$g(b)-unsaturated carboxylic acid or its salt, and acrylamide.
(FR)Additif destiné à la fabrication du papier et comportant (A) un polymère acrylamide cationique obtenu par la réaction d'un polymère acrylamide avec un hypohalite sous des conditions alcalines, à une température comprise entre 50 et 110 °C, et pendant une courte durée; et (B) soit une substance inorganique anionique soit un polyacrylamide cationique obtenu par la copolymérisation d'un monomère cationique tel qu'un ester acrylique ou un dérivé d'acrylamide, un acide carboxylique insaturé-$g(a),$g(b) ou un sel, et l'acrylamide.
