Title
(EN) PULP MIXTURE
(FR) MÉLANGE DE PÂTE À PAPIER
Abstract
(EN)
A pulp mixture includes a lignocellulosic material, water, lignin, an inorganic salt, and a copolymer including two or more structural units chosen from ethylene oxide units, propylene oxide units, (meth)acrylic acid units, ethyl acrylate units, and combinations thereof. The copolymer is free of silicone-containing structural units and the lignin is present in an amount of greater than about 150 ppm, based on a total weight of the pulp mixture.
(FR)
L'invention concerne un mélange de pâte à papier comprenant une matière lignocellulosique, de l’eau, de la lignine, un sel inorganique et un copolymère comprenant deux motifs structuraux ou plus choisis parmi les motifs oxyde d'éthylène, les motifs oxyde de propylène, les motifs acide (méth)acrylique, les motifs acrylate d'éthyle, et leurs combinaisons. Le copolymère est exempt de motifs structuraux contenant du silicone et la lignine est présente en une quantité supérieure à environ 150 ppm, par rapport à la masse totale du mélange de pâte à papier.
