| titleOfInvention | How to make paper and paperboard |
| abstract | The present invention relates to a process for the production of a sheet of paper and / or paperboard from a fiber suspension, characterized in that prior to the formation of said sheet two or more retention aids: (a) 2 meq.g - one or more water-soluble organic cationic polymer having a high cationic P1 than 1, and (b) at least one water-soluble ampholytic polymer P2 of at least one anionic monomer and at least one cationic monomer, Are added to the fiber suspension, respectively, at one or more injection points. The following polymerization techniques: - gel polymerization, - suspension polymerization, - Reverse emulsion polymerization, - dispersion polymerization, , The polymer P2 is added to the fiber suspension after it is dissolved in the aqueous solution. Polymer P2 has a factor F > 2. [The factor F is defined by the formula: F = UL2 x [(100-A) / (100-C) UL module and 0.1% by weight of polymer P2 in 1 M NaCl aqueous solution at 23 DEG C at 60 rev.min < -1 >, A and C correspond to the mol% of the anionic monomer and cationic monomer of polymer P2, respectively do)] |
