VERWENDUNG EINES QUATERNÄREN POLYAMMONIUMPOLYMERS FÜR DIE KONTROLLE VON ANIONISCHEN STÖRSTOFFEN UND HARZABLAGERUNGEN UND ZUR BEHANDLUNG VON GESTRICHENEM AUSSCHUSS

摘要

A method is disclosed for controlling anionic trash and pitch deposition and treating coated broke which comprises the step of adding a polyammonium quaternary to a pulp and papermaking system. The polyammonium quaternary, which may be either branched or crosslinked, comprises at least one cationic monomer, preferably diallyldimethylammonium chloride, and at least one branching or crosslinking monomer, preferably N,N,N-triallylamine or N,N,N-triallylamine hydrochloride.
