Method for preparing aqueous preparation containing acrylic comb type polymer solution and acrylic thickened emulsion, and use in the resulting mixture and paper coating

摘要

The present invention includes the steps of preparing an aqueous solution of a comb polymer of at least one functional group of a hydroxy polyalkylene glycol and a) alkoxy and / or is grafted to this (meth) acrylic acid; b) at least one mixed with additional water, optionally the aqueous emulsion in step b) the aqueous solution and by c) step a) and step; comprising the steps of preparing an aqueous emulsion of an acrylic thickening agent and may comprise from 5.5 and the fact that it includes the step of partially neutralized comb polymer during step c) steps a) and / or to obtain a mixture having a pH of 5.8 to 6.3 6.3, preferentially and more particularly wherein a, to prepare a composition. Also the product obtained in this way, and the invention, the gloss of the paper was coated with the slip and / or as a water retention agent in the slip and / or as a thickener for the slip in the paper coating slip and it is also directed to the use as a medicament for improving the optical bluing or /.
