摘要： The invention comprises a method for clarifying ink-laden water obtained from the recycling of paper stocks by treating said water with a conventional coagulant followed by treatment with a hydrophilic dispersion polymer. The hydrophilic dispersion flocculant of the invention is a copolymer of dimethylaminoethyl (meth)acrylate methyl chloride quat (DMAEA·MCQ) cationic monomer and (meth)acrylamide (AcAm). Following dosing with the flocculant, a floc is formed. The floc contains ink and impurities which are removed from the water process stream by means of solid liquid separation; the solid liquid separation comprising a dissolved air flotation method.

摘要： A papermaking process comprising forming an aqueous cellulosic papermaking slurry and adding a hydrophilic dispersion polymer to the slurry to increase retention and/or drainage is disclosed. The hydrophilic dispersion polymer comprises (a) a cationic monomer and (b) a second monomer represented by (meth)acrylamide (in an aqueous solution of a polyvalent anionic salt), wherein the polymerization is carried out in the presence of either an organic high-molecular weight multivalent cation comprising a water-soluble polymer containing at least one (a) monomer and/or poly diallyl dimethyl ammonium chloride (DADMAC). After addition of the polymers, the slurry is drained to form a sheet, and the sheet is dried.

摘要： A process for treating recycled coated broke which has been re-pulped to a slurry for the purpose of recycling the coated broke as cellulose fiber to the paper machine by the addition of a water-soluble polymer dispersion is claimed. The water-soluble polymer is formed by polymerizing a water-soluble mixture which comprises: (a) a cationic monomer represented by the following general formula (I):
wherein R 1 is H or CH 3 ; each of R 2 and R 3 is an alkyl group having 1 to 2 carbon atoms; R 4 is H or an alkyl group of 1 to 2 carbon atoms; A' is an oxygen atom or NH; B' is an alkylene group of 2 to 4 carbon atoms or a hydroxypropylene group; and X - is an anionic counterion; and (b) a second monomer represented by (meth)acrylamide (in an aqueous solution of a polyvalent anionic salt), wherein the polymerization is carried out in the presence of either an organic high-molecular weight multivalent cation comprising a water-soluble polymer containing at least one monomer of formula (I) and/or poly diallyl dimethyl ammonium chloride (DADMAC).
