The present invention relates to a method for polymerizing starch, degraded starch in an aqueous medium, at least one of the following monomers: acrylamide and / or methacrylamide, and at least one unsaturated mono- or dicarboxylic acid (s) To a water-soluble polymer composition. The polymer composition had an anionic net charge at pH 7 and a dry solids content of greater than 5 wt%. The present invention also relates to the use of such polymer compositions for surface sizing as well as surface sizing of paper, cardboard, etc., comprising the same. |
