摘要： A method for clarifying deinking process water in a papermaking process by using a water soluble graft copolymer having the structure:

wherein E is the repeat unit obtained after polymerization of an α, β ethylenically unsaturated compound, the molar percentage of a:b is from about 95:5 to 5:95, with the proviso that the sum of a and b equals 100%; G comprises the structure:

wherein

is the repeating unit of a cationic monomer, and maybe the same or different througout.
R₁, R₂ and R₃ are the same or different
and are hydrogen or a lower alkyl group having C₁ to C₃. F is a salt of an ammonium cation and the molar percentage of c:d is from 95:5 to 5:95 with the proviso that the sum of c and d equals 100%.
