Papermaking process utilizing hydrophilic dispersion polymers of diallyldimethyl ammonium chloride and acrylamide as retention and drainage aids |
摘要 |
A method for improving retention and drainage performance in a papermaking process is disclosed. The method comprises forming an aqueous cellulosic papermaking slurry, adding an effective amount of a hydrophilic dispersion polymer to the slurry, draining the slurry to form a sheet and drying the sheet. The hydrophilic dispersion polymer is preferably a copolymer of diallyldimethyl ammonium chloride and acrylamide. |
