The present invention refers to a process for sizing paper which comprises adding to an aqueous suspension containing cellulosic fibres, and optional fillers, (i) an anionic or cationic sizing dispersion; and (ii) a sizing promoter comprising a cationic organic polymer having one or more aromatic groups, and an anionic polymer having one or more aromatic groups, the anionic polymer being a step-growth polymer, a polysaccharide or a naturally occurring aromatic polymer, forming and draining the obtained suspension, wherein the sizing dispersion and sizing promoter are added separately to the aqueous suspension.
La présente invention concerne un procédé de collage de papier. Ce procédé consiste : - à ajouter à une suspension aqueuse contenant des fibres cellulosiques, et éventuellement des charges, (i) une dispersion de collage anionique ou cationique; et (ii) un promoteur de collage contenant un polymère organique cationique ayant au moins un groupe aromatique, et un polymère anionique ayant au moins un groupe aromatique, le polymère anionique étant un polymère à croissance étagée, un polysaccharide ou un polymère aromatique existant naturellement ; - à façonner et à drainer la suspension obtenue, la dispersion de collage et le promoteur de collage étant ajoutés séparément à la suspension aqueuse.
