ABSTRACT:
An improved papermaking process comprising forming an aqueous coated broke papermaking slurry and adding a blend of a water-soluble dispersion polymer and a coagulant to the slurry to increase retention and/or drainage is disclosed. After addition of the polymers, the slurry is drained to form a sheet, and the sheet is dried.
