العنوان (EN) PROCESS FOR MANUFACTURING PAPER
(FR) PROCEDE DE FABRICATION DE PAPIER
الملخص: front page image
(EN)The invention relates to a process for manufacturing paper and board comprising providing a suspension comprising cellulosic fibres and at least a sizing agent, dewatering said suspension thereby forming a paper−web, whereby an aromatic−containing cationic vinyl addition polymer, and an anionic polymer having a weight average molecular weight in the range of from 6,000 up to about 100,000 selected from the group consisting of vinyl addition polymers and condensation polymers is added to the suspension.
(FR)La présente invention se rapporte à un procédé de fabrication de papier et de carton qui consiste à utiliser une suspension comportant des fibres cellulosiques et au moins un agent de collage, et à déshydrater ladite suspension de manière à former une nappe de papier. Selon ledit procédé, un polymère d'addition, vinylique, cationique, contenant des éléments aromatiques, et un polymère anionique ayant un poids moléculaire moyen en poids compris entre 6 000 et 100 000 environ et sélectionné dans le groupe constitué par des polymères d'addition vinyliques et des polymères de condensation, sont ajoutés à la suspension.
