Aqueous silica-containing composition |
| abstract |
The present invention relates to an aqueous silica-containing composition comprising an anionic organic polymer having at least one aromatic group and anionic aggregated or microgel formed silica-based particles. The aqueous silica-containing composition contains the anionic organic polymer having at least one aromatic group and the anionic silica-based particles in an amount of at least 0.01% by weight of the total weight of the aqueous silica-containing composition. The aqueous silica-containing composition contains substantially no cellulose-reactive sizing agent and the anionic organic polymer having at least one aromatic group is not an anionic naphthalene sulphonate formaldehyde condensate. n The invention further relates to methods for the preparation of the aqueous silica-containing composition and the use of the aqueous silica-containing composition as a drainage and retention aid in a process for the production of paper. The invention also relates to a process for the production of paper from an aqueous silica-containing composition and at least one charged organic polymer are added to the cellulosic suspension. |
