Beschreibung
Zusammenfassung:	A method of making paper comprising adding to an aqueous suspension of cellulosic pulp slurry a polymer in the form of an inverse emulsion comprising a cationic poly N,N-(dialkylaminoalkyl) (meth)acrylamide or it's quaternates or salts, and dewatering the cellulose pulp slurry to form a paper or paperboard product, wherein the pulp slurry contains more than about 75 weight ppm of water soluble lignin based upon total pulp slurry weight, and wherein the polymer optionally contains a multi-functional monomer. L'invention concerne un procédé de fabrication de papier consistant en l'ajout, dans une suspension aqueuse de pâte liquide de cellulose, d'un polymère sous la forme d'une émulsion inverse comprenant un poly N,N-(dialkylaminoalkyle) (méth)acrylamide cationique ou ses constituants quaternaires ou ses sels, et la déshydratation de la de pâte liquide de cellulose pour former un produit en papier ou en carton, la pâte liquide contenant plus d'environ 75 ppm en poids de lignine soluble dans l'eau sur la base du poids total de la pâte liquide, et le polymère contenant éventuellement un monomère multifonctionnel.
