| titleOfInvention | Copolymer Mixing Composition Used to Increase Paper Filler Content |
| abstract | In the process of preparing a heterogeneous polymer mixture comprising at least one anionic polymer, at least one cationic polymer, and at least one non-ionic polymer, the method comprises the following steps: (a) Ratio Adding a first dose of polymerization initiator and one or more anionic or cationic monomers to the neutral solution, wherein each monomer has the same charge; (b) adding a second dose of polymerization initiator and one or more non-ionic monomers; (c) adding a third capacity of polymerization initiator and at least one ionic monomer having a charge opposite to that of step (a); (d) adding a fourth capacity of polymerization initiator dropwise to react all remaining monomers; And (e) neutralizing the resulting heterogeneous polymer mixture. Also claimed are heterogeneous polymer mixtures containing polymers formed of at least one anionic, cation, and non-ionic monomer that are in-situ polymerized or separately polymerized and then mixed. Also claimed is a method of increasing the filler content of a paper or cardboard sheet, the method comprising the steps of: (a) mixing a heterogeneous polymer mixture and a precipitated calcium carbonate filler; (b) mixing the resulting mixture with the pulp slurry; And (c) processing the resulting pulp slurry mixture to form a paper or cardboard sheet. Finally, a method of increasing the filler content of a paper or cardboard is claimed, the method comprising the steps of: (a) mixing a pulp slurry with either a heterogeneous polymer mixture or a precipitated calcium carbonate filler; (b) mixing the remaining ingredients with the pulp slurry; And (c) processing the resulting pulp slurry mixture to form a paper or cardboard sheet. |
